this is al jazeera america. live from new york city, i'm erika pitzi. the head of the epa says the agency is working non-stop to clean up a major toxic waste spill in colorado. gina mccarthy is visiting sites along the rivers. the agency is expected to release testing results from samples of polluted water. she said her agency takes full responsibility after a crew accidentally triggered the leak. >> it is a tragic and unfortunate accident, and epa is taking responsibility to ensure it is cleaned up. the most important thing is ensuring the health and safety of the residents and visitors near the river. >> reporter: the spill is still flowing at a rate of up to 700 gallons mant. today contaminated water is expected to reach lake powell.

the agency along with local scientists say there is no immediate threat, though. the states of colorado and new mexico and now any navajo nation have declared a state of emergency as a result of the spill. the rivers snake west forming a natural boundary for the tribal nation. the leaders say the rivers are more than just water sources they are sacred. >> reporter: they are forming plans to deal with t-- the potential impacts. meanwhile residents are being told to stay away from the river until further testing can be done. >> this is what we refer to as the bloom. this field is starting to bloom early because it's not drawing up the moisture. >> reporter: lorenzo heads the

navajo nation council. aside from raising cattle and horses, he -- depends on this alpha fa field. >> it is speaking to me, saying i have these problems. i don't have enough water. i'm not drawing up the nutrients, so cut me or else i'm going to die. >> reporter: the tainted water flowing south also means he has to keep his horses and cattle from the river and give them water from a nearby municipal line. the toxic discharge is full of heavy metals. now those living town stream are preparing for the worst. in farmington, new mexico officials are encouraging residents to bring water samples from home to be tested. ryan flynn is secretary of the new mexico environment department, he says so far it

doesn't look like the spill has affected drinking waters. >> we're just going to focus on the chemistry of the river, that will help us know when it is safe to use the water again. >> reporter: both new mexico and navajo nation have declared states of emergency. >> i don't know how soon it will be before it stops. those are questions we have been asking the epa. can they stop this and what technology can they used to treat the water as it is coming out. >> reporter: the navajo nation announced it is planning lawsuits against the epa and the mine. meanwhile people are starting to count their losses while waiting on news on whether the water is safe to use or not. there are farmers all the way

down this valley. what does that mean to us as farmers and ranchers? what does it mean to the health and safety of people that use it for drinking water. now earlier today we talked with jonathan freeman a professor at the university of louisville school of medicine. he said anyone using the river for farming should be concerned. >> there have been reports out of china about rice being irrigated with contaminated water, and the people suffer from metal toxicity. all of the food that the navajo nation is growing should be tested, especially like green leafy vegetables and grains, they are almost magnets for take up some of these metals. >> he also says the metals are in their most elemental state so

it's unlikely they will degrade over time. hillary clinton may be in trouble in an early primary state. a poll has senator bernie sanders jumping ahead of clinton by 7 percentage points in new hampshi hampshire. this is the first time sanders has registered a lead over clinton. hillary clinton says she will now do what she has refused to do for months, hand over her personal email server to the justice department. this comes as questioning swirl about how classified files made it on to that server. john henry smith has the details. >> reporter: hillary clinton's announcement that she will hand over her personal email server to the justice department is a stark departure of the position she has maintained for five months. >> reporter: the server contains personal communications from my husband and me, and i believe i

have met all of my responsibilities, and the server will remain private. >> reporter: the clinton campaign says she now is also giving investigators 3 thumb drives containing roughly 30,000 emails relating to her work. the fbi is investigating whether her use of a personal email account and private server resulted in the mishandling of any classified information. just hours before the announcement, a state department report said that two of the emails on clinton's server have been classified as, quote, top secret, though it also acknowledged that the material was not marked that way at the time the emails were sent. clinton has long denied any type of classified emails ever existed on her personal server. >> i'm certainly well aware of the classification requirements, and did not send classified material. >> reporter: republicans, including house speaker john boehner welcomed clinton's

decision. in a statement, boehner said, quote: john henry smith, al jazeera. republican presidential candidate jeb bush delivered a major foreign policy address that calls for greater u.s. involvement in the fight against isil. michael shure reports. >> reporter: in a campaign that has been dominated by bluster and distraction, former florida governor, jeb bush tried to bring some serious conversation to the race in a speech at the ronald reagan presidential library. >> good things happen when america is engaged with friends and allies, alert to danger, resolved to deal with threats before they become catastrophes. >> reporter: that was a hallmark of his speech, calm, yet resolved, delivered in building dedicated to a president who embodied those straights.

but he also took a page from a successful republican play book. >> the reality is that radical islam has been spreading across the middle east, throughout africa, and parts of asia. even in the nations in the west. >> reporter: some of the younger members of a decidedly older audience who saw the speech agreed that people should be scared. >> it's a scarey situation when you factor in the social media. that's what makes them so dangerous. the fact you can do a quick google search and there it is. >> reporter: the speech had been anticipated by political analysts as a needed forum for governor bush where he could put space between his foreign policy and that of his brother. in setting the table to what he sees is the global threat the next president will face, bush was clear that it wasn't a mess that his brother left by going

in, but rather that the obama administration left by leaving too quickly. >> isis grew while the united states disengaged from the middle east and withdrew. and where was secretary of state clinton in all of this? she opposed the surge, and then joined in claiming credit for its success, then stood by as that hard-won victory by american and allied forces was thrown away. >> reporter: in response he outlined an ambitious five-point plan on how he would deal with iraq which included the use of more ground forces. and his plan for syria, and iran, where he rejected the nuclear deal. >> it is a deal unwise in the extreme with a regime that is untrustworthy in the extreme. it should be rejected by the congress of the united states of america. [ applause ]

>> reporter: immediately following his speech, donald trump went on fox news and once again may have stolen the attention from jub bush, something the government for himself may be beginning to fear. coming up, flash point ferguson, new video said to be of the gunman shot by police during a rally this week. and the desperate plea of a hung rer striking inmate held at guantanamo for the past 14 years.

state of emergency in still in place in ferguson, missouri, despite a more peaceful night of protests. but there is some controversy vournding newly released surveillance video. police say the video shows the man they shot earlier this week, apparently holding a gun. >> reporter: the surveillance video released last night is pretty remarkable in how clear it is. it appears to show the 18 year old pulling a gun out of his

waistband, but it does not show officers shooting him nor him shooting at officers. his father argued that he actually wasn't even armed that night. in the meantime the protests here last night, a fifth night of protests were much calmer than nights before. a couple dozen protests issers marched past police, but they held back for the most part, and in the end it all broke up fairly peacefully, and there were no arrests. also, though, last night, there was another appearance of the oath keepers, a very anti-government militia-type group, very promilitary that has talked often about upholding second amendment rights. they were walking arrange with military-type assault weapons. the police and protesters

clearly did not want them there. and we caught an exchange between one of the protesters and one of the oath keepers. >> i'm protecting these gentlemen so they can document what is going on -- >> if the press had been attacked by the police -- sir, if these officers come over here and rush the police, you are going to protect them. >> if they come over and you are visiting with me and they started harassing you, i would defend you. >> reporter: but there were no confrontations. no arrests in ferguson. a white police officer who shot an unarmed black teenager in arlington, texas has been fired from the department. the 19 year was killed during a burglary investigation at a car

dealership. >> we got shots fired. [ inaudible ] >> the recording is show nearly two minutes lapsed between police arriving and shots being fired. officer brood miller shot at taylor four times during a pursuit. the police chief calls the initial chase, quote, questionable. >> he's a kid that made a mistake and it cost him dearly, so -- nobody should have to go out that way. >> a criminal investigation is now underway. an advocacy group is appealing for fair treatment of officer miller, emphasizing that the police chief's own acknowledgment, the investigation is still incomplete. a federal jail has denied bail for a young couple that allegedly tried to join isil.

they were arrested in mississippi just before taking off for syria. they are charged with attempting and conspiring to provide material support to a terrorist group. in another case possibly connected to isil a florida man has pleaded not guilty in a plot to bomb a beach. he said he wanted to detonate a backpack full of nails in miami. >> the second charge is attempt to provide material support to a terrorist organization. it relates in my estimation to the allegation of a recruitment video. harlem is doing marginally better. he has a chance to correspondent pond with his family through letters. >> reporter: he was arrested in july after allegedly taking an explosive device from an

undercover fbi agent. >> reporter: president obama's promise to close the prison camp at guantanamo bay before he leaves office has run into yet another roadblock. >> reporter: it was one of the first promises the president made. he campaigned on it and repeated it many times in the past seven years. he signed an executive order to close the guantanamo bay detention center as soon as practicable. but so far the pentagon has failed to come up with a plan to make it happen. the obama administration has failed to present a concrete plan to congress so that congress can lift restrictions that have so far stymied the closure. one idea was to send the detainees that the pentagon says cannot be released or sent to other countries to a federal prison in illinois that has some 1500 empty cells. but as reported by the

"washington post" the obama administration forgot that former attorney general eric holder promised the senate judiciary committee, quote: so it's back to the drawing board. >> we obviously strongly support this secretary, strongly supports president obama's determination made from the very first day of his administration to close guantanamo. it's obviously a top priority. it has remained a challenge throughout. >> reporter: the administration had hoped to get a plan to senate armed services committee chairman this month before congress recessed. but now officials say it will be next month at the earlierest before a proposal goes to the hill. mccain has promised to work with president obama to close guantanamo, but only if the administration can provide an alternative that addresses congressional concerns.

it's not just the current ban on moving any prisoners to u.s. soil that has to be addressed, it's also the requirement that the defense secretary sign off on any transfers to other countries, essentially certifying that the vetteled detainees no longer pose a risk to the u.s. that was a source of tension between former defense secretary chuck hagel, and the white house last year, because hagel was often reluctant to give his personal assurance of something that was unknowable. current defense secretary, ash carter is also taking a conservative approach. six years after president obama signed an executive order to close guantanamo within a year, the number of detainees has been cut from 240 to 116. and nearly half have been cleared for release, with most not facing any charges. the state department says it is working full-time to find countries who will take guantanamo prisoners, many of whom were cleared for release years ago, but have nowhere to

go. meanwhile the white house is still searching for a prison in the u.s., willing to accept what it calls thor reducible minimum, the several dozen detainees judged too danger to ever be released. among the prisoners who were cleared for release years ago is this inmate. the yemeni native has been in guantanamo for 14 years and on a hunger strike since 2007. force fed through a feeding tube he reportedly weighs only 75 pounds now. the obama administration is divided over what to do with the case. his lawyer spoke to randall pinkston. >> by the unanimous determination of six national security agencies, the office of joint chiefs of staff, department of defense, justice, homeland security, all of the agencies that u.s. citizens rely on to keep him safe have said

that he can leave. >> why has he not been allowed to leave? >> that question is playing right now right real time in washington, d.c. i filed a motion for his release and asked the government not to oppose it, to speed his release so he can get medical care. and it appears that the department of defense is blocking this solution. >> the justice department has until august 15th to respond to the prisoner's petition. stay tuned for special coverage, out of cuba this freye as the u.s. flag begins to fly over the embassy in havana. antonio mora hosts a special hour of live coverage, beginning at 9:00 eastern. coming up, painting the blues away. we'll take do you a mexico town trying to revamp its gritty image one stroke at a time. ♪
