The House Freedom Caucus officially condemned Rep. Justin Amash (R-Mich.) on Monday night for saying President Trump "has engaged in impeachable conduct" over the Mueller report, The Hill first reported.

Details: Former Freedom Caucus chairman Rep. Jim Jordan (R-Ohio), the top Republican on the House Oversight Committee, told reporters every Caucus member in attendance opposed the comments made by Amash, who was not present at the meeting, per Politico.

Why it matters: Amash is the first Republican congressman to speak out in favor of impeaching Trump.

The big picture: Michigan state Rep. Jim Lower announced Monday he'd challenge Amash for his seat because of his remarks on Trump, the Detroit Free Press reports.

Why it matters: In a time of unprecedented colliding crises for the nation, the polling considered Biden to be vastly more competent.
