WASHINGTON — After last week's deadly assault on the U.S. Capitol by supporters of President Donald Trump, members of Congress are expressing something once unthinkable: that some of their own colleagues may be endangering their lives. Not in a rhetorical sense, but in a direct and immediate way. "It's the most poisonous I've ever seen," Rep. Don Beyer, D-Va., said in an interview. "There's the overall sense that maybe if some of them have guns — and likely the ones who are more into conspiracy theories and QAnon with the pedophilic satanic rings — are we safe from them?"
