WASHINGTON (AP) — President Donald Trump on Tuesday turned up the pressure on governors to quell the violence set off by the death of George Floyd, demanding New York call up the National Guard to stop the “lowlifes and losers.”

As more demonstrations began taking shape around the country, and cities including Washington prepared for another possible round of scattered violence after dark, the president amplified his hard-line calls of a day earlier, in which he threatened to send in the military to restore order if governors didn’t do it.

“NYC, CALL UP THE NATIONAL GUARD,” he tweeted. “The lowlifes and losers are ripping you apart. Act fast!”

One day after a crackdown on peaceful protesters near the White House, thousands of demonstrators massed a block away from the presidential mansion, facing law enforcement personnel standing across a black chain-link fence. The fence was put up overnight to block access to Lafayette Park, just across the street from the White House.

“Last night pushed me way over the edge,” said Jessica DeMaio, 40, of Washington, who attended a protest Tuesday for the first time. “Being here is better than being at home feeling helpless.”

The crowd remained in place after the city’s 7 p.m. curfew passed, defying warnings that the response from law enforcement could be even more forceful. At one point, the crowd booed when a protester climbed a light post and took down a street sign. A chant went up: “Peaceful protest!”

Protests ranged across the U.S., including New York City, Los Angeles, Houston, St. Paul, Minnesota, Columbia, South Carolina, and Orlando, Florida, where more than 1,000 people gathered in the afternoon to decry the killings of black people.

“This has to change,” said 39-year-old Aisxia Batiste, an out-of-work massage therapist in Orlando. “Something has to give. We’re done. This is the beginning of the end of something. It has to be.”

In New York, midtown Manhattan was pocked with battered storefronts after Monday’s protests. Macy’s flagship store was among those hit when crowds of people smashed windows and looted stores as they swept through the area. A police sergeant was hospitalized after being hit by a car in the Bronx, where people walked Tuesday between ransacked buildings and a burned-out car on the Grand Concourse, a commercial thoroughfare.

Police made nearly 700 arrests and Mayor Bill de Blasio extended an 8 p.m. curfew all week.

“We’re going to have a tough few days,” he warned, but added: “We’re going to beat it back.” He pleaded with community leaders to step forward and “create peace.”

More than 20,000 National Guard members have been called up in 29 states to deal with the violence. New York is not among them, and De Blasio has said he does not want the Guard. On Tuesday, Democratic Gov. Andrew Cuomo called what happened in the city “a disgrace.”

“The NYPD and the mayor did not do their job last night,” Cuomo said at a briefing in Albany.

He said the mayor underestimated the problem, and the nation’s largest police force was not deployed in sufficient numbers, though the city had said it doubled the usual police presence.

Tuesday marked the eight straight night of the protests, which began in Minneapolis, where Floyd died, and quickly spread across the country.

On Monday, scattered violence flared in multiple protests, including an officer who was shot and gravely wounded as police tried to disperse a crowd outside a Las Vegas hotel and casino, and four officers shot in St. Louis. They were expected to recover. In Philadelphia, officials said one person was killed trying to use explosives to open an ATM, and a gun shop owner fatally shot a would-be thief. A 19-year-old died of injuries suffered during looting.
