democrats wanted to strike a thoughtful tone at the convention, did that resonate? >> not all good news for democrats on that front because voters told us they would have liked to hear more about the economy, about changing washington and about terrorism all critical issues for voters. and that's another reason why this race remains so tight. >> quijano: >> quijano: donald trump got tangled up in a new war of words this weekend with the muslim father of a fallen u.s. soldier. errol barnett has the latest from washington. >> he is a black soul, and this is totally unfit for the leadership of this beautiful country. >> reporter: speaking on cnn today, khizr khan resumed his criticism of donald trump. khan is the muslim father of fallen u.s. army captain, humayun khan, who received a bronze star and purple heart after being killed in iraq. khan bashed trump in a speech at the democratic convention,

challenging the republican presidential candidate to read the constitution. >> you have sacrificed nothing! >> reporter: when asked about khan's comments on abc, trump disagreed. >> i think i've made a lot of sacrifices. i work very, very hard. i've created thousands and thousands of jobs, tens of thousands of jobs, built great structures. >> reporter: his answer was mocked online this weekend, as hashtag "trump-sacrifices" started trending on twitter. a pocket version of the u.s. constitution rose to best-seller status on amazon. and, today the fallen captain's mother responded in an on op-ed in the "washington post." she wrote, "donald trump has asked why i did not speak, because without saying a thing, all the world, all america, felt my pain." >> he had to take that shot at her. this is height of ignorance. >> reporter: today, hillary clinton weighed in. >> to have trump do what he did,

i don't know where the bounds are, i don't know where the bottom is. >> reporter: donald trump fired off several tweets today saying he was "viciously attacked" by mister khan adding "am i not allowed to respond?" trump also acknowledged that khan's son is a hero, apparently hoping to end this war of words, elaine. >> quijano: errol barnett in washington, thank you. there was >> quijano: there was gunfire in austin, texas overnight. one woman was killed, four others wounded. someone opened fire on a crowd, as people were clearing out of nightclubs. no word yet on a motive. in maryland, at least two people are dead after floodwaters swept through the historic town of ellicott city. this was the dramatic scene last night as rapids ran through the streets. people formed a human-chain to rescue a woman trapped in her car. nearly six inches of rain fell in two hours.

homes and businesses are devastated. a new wildfire broke out this weekend near fresno, california. it quickly burned more than a thousand acres, and forced hundreds of people from their homes. farther north, a deadly and destructive fire continues to grow near the coastal town of big sur. fires are burning across the west, in at least ten states. overseas in poland, what's known as the "catholic woodstock" ended with a tremendous sunday mass, and parting words of wisdom from pope francis. seth doane was there. >> reporter: well over a million people camped out overnight to catch a glimpse of pope francis. he sped through the crowds under tight security. the pontiff celebrated mass this morning for the faithful who flew flags of the 187 countries they represented. he told them not to see borders as barriers and to reject hatred

among people-- a message particularly relevant amid europe's migrant crisis. many walked for miles to get to the mass and spent the night praying in an open field. the pope on saturday had warned the faithful against being couch potatoes-- in particular, "those sofas we have nowadays with a built-in massage unit to put us to sleep." too many young people today, he worried, escape to the world of video games and computer screens instead of being engaged. at one point during these celebrations the pope asked the masses gathered, from so many different countries, to hold hands. and seek common humanity. it underlined a message he's had all week: find that which unites, not divides.

>> quijano: just north of boston, the town of somerville, massachusetts is divided over a "black lives matter" sign. it's been up for more than a year.

michelle miller tells us why some want it taken down. >> reporter: dozens of protestors gathered outside somerville city hall thursday, demanding that the "black lives matter" banner out front be taken down. the banner went up a year ago, designed to open a conversation about race in the community. but the murders of police in baton rouge and dallas tested the tolerance here. mike mcgrath heads up the local police union. >> our message is simply "life matters." we don't want to exclude any population in the united states >> reporter: rachel miselman is a local eduactor. should that banner come down? >> that banner should definitely come down. black lives matter is predicated on the idea that you have police officers that are so consumed by hatred that they would take the life of another.

>> reporter: black lives matter held its own gathering a mile away. stephanie guirand is one of the organizers. >> how many people have to die on camera for us to understand that black lives don't matter in this country? i'm sorry, i'm very emotional about this topic. >> reporter: some somerville residents like michael johnson see both sides. >> no one wants to see a cop shot and killed. but black lives matter doesn't represent that. i'm totally pro-police, but i totally understand black lives matter. >> reporter: somerville's mayor joseph curtatone says the sign will not come down. the conversation, he says, must continue. >> if we're going to be a more stronger civilized society, then we have to have the conversation. it will be difficult, it will not be easy, but we'll be more civilized for it. >> reporter: a sign of the times in a town divided. michelle miller, cbs news, somerville, massachusetts. >> quijano: up next, a new report finds serious health risks from dietary supplements.

emergency room. doctors said the supplements were the likely culprit. >> i had no idea about the risks of supplements and no one discussed them with me. >> reporter: cimorelli is one of the roughly 200 million americans taking dietary supplements. today consumer reports identified 15 commonly-used supplement ingredients that could be potentially harmful to many of them. some examples: red yeast rice to lower cholesterol may cause kidney and liver problems. green tea extract powder for weight loss may elevate blood pressure and cause liver damage. and kava to reduce anxiety may exacerbate depression. one area of concern is supplements do not undergo the rigorous regulatory scrutiny applied to prescription drugs and other over-the-counter medicines. dr. pieter cohen of harvard medical school. >> the problem is supplements look just like these drugs on store shelves, but the requirements to get a supplement on the store shelves is nothing compared to what it takes to sell aspirin or tylenol. >> reporter: dr. aida vega is an internist at mount sinai hospital. she says that doctors and

patients often don't discuss supplements, which can lead to problems. how important is it for physicians to ask patients about supplement use? >> the most important part is to understand why they're taking it, because if you understand why they're taking it you can steer them in the proper direction. >> reporter: the supplement industry says overwhelmingly supplements are safe and play a valuable role. but doctors worry lax regulation and enforcement means products could be contaminated, mislabeled, or interact in dangerous ways with prescription medication. dr. tara narula, cbs news, new york. >> quijano: still ahead, they can't even walk yet, but they're learning how to swim.
