minneapolis turned violent. people storming an evacuated police precinct setting it on fire. the national guard activated after prosecutors say they're not yet ready to press charges in the death of george floyd. an estimated 4,000 people marched peacefully through minneapolis earlier. but as night fell, other protesters set fires destroying that third police precinct and businesses. more than 30 fires were set the previous night. target is now temporarily closing 24 stores in the twin cities after people were seen looting some of its stores in the area. >> hey, hey, hey. >> reporter: new video shows a woman in a wheelchaired pumped and sprayed with a fire ex-ti extinguisher after she tried to block protesters from entering one of those stores. >> leave her alone. leave her alone. >> reporter: the city is now suspending public transportation through the weekend.

and now the protest spreading to more cities across the country including new york city where police arrested at least 40 people. in los angeles and in denver, dozens gathered at the state capitol. >> move, move. >> reporter: shots were reportedly fired, and one person was hit by a car. many of the demonstrators chanting "i can't breathe," some of the final words uttered by floyd monday night when video shows him on the ground handcuffed then losing consciousness with minneapolis officer derek chauvin's knee digging into his neck. transcripts from a newly released 911 call show police were called to the scene after a store employee accused floyd of trying to use counterfeit money. four officers in the video have been fired including chauvin. abc news has learned that chauvin had 18 prior complaints filed against him, two of them required discipline. thursday prosecutors said they won't rush to press charges in floyd's death. >> we are conducting a robust

and meticulous investigation into the circumstances surrounding the events of may 25th, 2020 and the police officer's actions on that evening. >> reporter: the president says the justice department and fbi are investigating along with county prosecutor mike freeman. freeman later clarified this comment he made regarding evidence in the case. >> my job in the end is to prove that he violated a criminal statute and there is other evidence that does not support a criminal charge. >> reporter: this morning freeman's office says his remark on other evidence is being misinterpreted saying it was critical to review all the evidence because at the time of trial invariably all that information will be used. a former federal prosecutor says if anyone is charged in floyd's death, the announcement is likely months away. >> if they were to present a job that was, you know, maybe half done to a jury, they're not going to say, you know, please

forgive some of the evidentiary holes in my case, i was really in a hurry. nobody is going to care. >> and a nightclub owner in minneapolis says chauvin and floyd both worked as security officers at his club last year but he says he's not sure if they knew each other. a major fire was also burning in the city of st. paul. reporter beth mcdonough from our minneapolis station was there. >> reporter: police officers out here at the scene tell us that rioters have essentially been torching some of these buildings. they've been going up and down university nsacking business, vandalizing businesses, looting businesses. we've seen a grocery store targeted, a target store targeted. we know that fires were set at a u.p.s. store, a verizon store, business after business, at least a dozen of them we know at this point, and just recently police and firefighters had set up a perimeter here on university, and that is to keep

the suspected looters and rioters as far away from this fire as possible. >> and beth says a neighborhood nearby was evacuated because of those fires. president trump weighed in overnight on the protests in minneapolis criticizing the mayor calling him very weak. the president also tweeted, these thugs are dishonoring the memory of george floyd, and i won't let that happen. just spoke to governor tim walz and told him the military is with him all the way. any difficulty and we will assume control but when the looting starts, the shooting starts. moments ago, the mayor of minneapolis responded to trump's criticism. >> weakness is refusing to take responsibility for your own actions. weakness is pointing your finger at somebody else during a time of crisis. donald trump knows nothing about the strength of minneapolis. >> reporter: the mayor called for peace and calm in the city. meanwhile, twitter has now

voting by mail including when he declared there is no way, zero, that mail-in ballots will be anything less than substantially fraudulent. overnight trump tweeted again on the issue writing, mail-in voting will lead to massive fraud and abuse. it will also lead to the end of our great republican party. according to numerous investigations, there's no evidence of widespread voter fraud in america. abc's jonathan karl pressed the president on his claims thursday. >> but when they send out like in california millions and millions of ballots to anybody that's breathing, anybody in california that's breathing gets a ballot. >> but, mr. president, that's not true. you know goffin newsom, governor newsom has not sent out ballots to everybody in california. they're only going to registered voters. >> how many are there? >> so what your tweet said was not wrong -- was not correct. it was wrong. >> oh, really? >> reporter: the president was then asked why he continues to use twitter while criticizing

the site's policies. >> if we had a fair press in this country, i would do that in a heartbeat. there is nothing i'd rather do than get rid of my whole twitter account. >> reporter: it's not clear the president has the power to change liability protection laws. without congress even the president acknowledges the order will likely be challenged in court. kenneth and mona. >> all right, ines, thank you. now to the president's democratic rival. some advice for former vice president joe biden as he looks for a running mate. a top democratic pollster says senator elizabeth warren is the best choice for biden because she could help him gain millennials. biden hopes to name his choice around august 1st. well, coming up, new concern for those with diabetes and their risk for covid-19. but first the so-called murder hornet now showing up in new places. en every day. people are surprising themselves the moment they realize they can du more

undergoing investigation to ensure its accuracy of test results when performed by health care providers but the fda seems optimistic and i think an accurate home testing option would be great for all. >> we have new information this morning about diabetics and this virus and a study finds one in ten diabetic patients with covid-19 died within a week of being hospitalized. what's the takeaway here? >> it's a good question and to some extent we know that anyone with diabetes is already at increased risk and may have difficulty fighting any infection because of their compromised immune system, so this study essentially confirms the same is true for covid. >> looking at washington state hit early on with the first confirmed cases, now we're learning about half of newly diagnosed coronavirus cases there are people under age 40. why are we seeing this? >> at the beginning of testing we had very limited and strict criteria for who we were able to test through the department of public health. most of those who met the

criteria at that time had to be severely or critical ill and it continues to be to this day that the older or elderly population are those who are the sickest. so now with broader testing criteria and an increased testing capacity, more equipment, more are getting tested who have milder illnesses. >> our thanks to dr. garabogian there. still to come, big news about those free samples at costco. plus, the reunion between two cousins that you have to see next. than rheumatoid arthritis or psoriatic arthritis. when considering another treatment, ask about xeljanz xr, a once-daily pill for adults with moderate to severe rheumatoid arthritis or active psoriatic arthritis for whom methotrexate did not work well enough. it can reduce pain, swelling, and significantly improve physical function. xeljanz can lower your ability to fight infections like tb; don't start xeljanz if you have an infection. taking a higher than recommended dose of xeljanz for ra can increase risk of death.
