The National Park Service said it has received three separate applications for pro-Trump protests on Tuesday or Wednesday, with estimated maximum attendance at 15,000 people. Experts who monitor extremist groups fear the demonstrations could bring more chaos and violence to the US capital, the Washington Post reported, including renewed violent attacks by the Proud Boys on leftwing counterprotesters. The US capital has mobilized the national guard ahead of the planned protests. Mayor Muriel Bowser requested a limited national guard deployment to help bolster the metropolitan police department, and has asked local area residents to stay away from downtown DC. “There are people intent on coming to our city armed,” said DC acting police chief Robert Contee on Monday. During a presidential debate in September, Trump was asked to condemn the Proud Boys, and other violent rightwing groups linked to white supremacy, and instead told the group to “stand back and stand by”, because “somebody’s got to do something about antifa and the left”. Over the weekend, Trump retweeted a promotion for the rally with the message, “I will be there. Historic Day!” At a November rally, which drew about 15,000 people, Trump staged a limousine drive-by past cheering crowds in Freedom Plaza, on the city’s iconic Pennsylvania Avenue. And at the December rally, which drew smaller numbers but a larger contingent of Proud Boys, Trump’s helicopter flew low over cheering crowds on the National Mall. Tarrio’s arrest was first confirmed by the New York Times.
