National Guard Summoned to Aid US Cities Amid Police Clashes Associated Press ATLANTA - Protesters burned businesses in Minneapolis. They smashed police cars and windows in Atlanta, broke into police headquarters in Portland, Oregon, and chanted curses at President Donald Trump outside the White House. Thousands also demonstrated peacefully, demanding justice for George Floyd, a black man who died after a white officer pressed a knee into his neck. As anger over Floyd's killing spread to cities nationwide, local leaders increasingly said they could need help from National Guardsmen or even military police to contain the unrest. Georgia's governor declared a state of emergency early Saturday to activate the state National Guard as violence flared in Atlanta. Portland Mayor Ted Wheeler also declared an emergency and ordered a nighttime curfew for the city. Another 500 Guard soldiers were mobilized in and around Minneapolis, where Floyd died and an officer faced charges Friday in his death. But after another night of watching fires burn and businesses ransacked, Minnesota Gov. Tim Walz said early Saturday that he was moving to activate more than 1,000 more and was considering federal help. The Guard was also on standby in the District of Columbia, where a crowd grew outside the White House and chanted curses at President Donald Trump. Some protesters tried to push through barriers set up by the U.S. Secret Service along Pennsylvania Avenue, and threw bottles and other objects at officers wearing riot gear, who responded with pepper spray. "I just feel like he's just one of many names that we've had to create hashtags and T-shirts and campaigns for and I feel like nothing has changed," district resident Abe Neri said of Floyd. "And so that's why I'm out here. Yeah, when you say nothing you're taking the side of the oppressor." .
