A “Justice for J6” event at the Union Square area of the Capitol grounds has been organized by a nonprofit group led by former Trump campaign operative Matt Braynard to protest charges against January 6 rioters. Braynard has assured authorities that the rally will be peaceful, but D.C. police have expressed fears that it will quickly turn violent.

“This is America, they can peacefully assemble, they can celebrate what they want. But Americans should know that in a couple of weeks, Republicans are going to come to the Capitol to celebrate cop killers,” the California Democrat told host Jim Acosta on CNN Newsroom Saturday.

“These unmasked individuals celebrating cop killers, creating more and more [COVID-19] mutations that are threatening our kids will be in Washington D.C. We just have to make sure that if they are ready to get violent that we’re ready again in a better way than on January 6 to defend the Capitol,” Swalwell added.
