A progressive activist on Tuesday interrupted President Donald Trump’s arrival to Senate Republicans’ weekly lunch by throwing Russian flags and shouting, “Trump is treason.” Trump was walking beside Senate Majority Leader Mitch McConnell.

“Why are you talking about tax cuts when you should be talking about treason?” Ryan Clayton shouted from the press pool. “Why is Congress talking about tax cuts when they should be talking about treason?”

He was standing directly to the left of this reporter from The Intercept:

Clayton also accused the president of conspiring with Russian agents to steal the election before being escorted out by police.

Clayton is head of the group Americans Take Action and, as the name suggestions, is no stranger to direct-action tactics. At the most recent Conservative Political Action Conference, Clayton tricked right-wing activists into waving Russian flags while Trump spoke.

He was also involved in a high-profile incident with conservative provocateur James O’Keefe, when Clayton secretly filmed O’Keefe’s speech at a fundraiser, and then interrupted it by breaking into song. He was dragged down the steps and tossed from the event.

Clayton, unsurprisingly, did not immediately respond to a request for comment.
