MADISON, Wis. (AP) — U.S. Sen. Ron Johnson’s refusal to rule out a challenge of Electoral College results in Congress is leading to widespread Democratic criticism. Incoming state Rep. Francesca Hong of Madison called the Republican “delusional scum” on Thursday. Democratic U.S. Rep. Mark Pocan tweeted that Johnson is “Wisconsin’s biggest embarrassment.” Johnson plans a Senate committee hearing on what he says were “irregularities” with the election. Republicans who control the Wisconsin state Legislature have scheduled a similar hearing for Friday. Democratic Gov. Tony Evers said the hearings will be more of the same “crap,” where people with no first-hand knowledge make baseless allegations.
