Kinzinger blasts GOP colleagues' silence after Gonzalez announces retirement

• "If you think Trump runs our party, you own his comments, or you must denounce them. If you think he doesn't lead our party, you must publicly say that. The time for hiding is over, the stakes are too high," Kinzinger said.

Driving the news: Kinzinger, one of Trump's fiercest Republican critics, was also one of 35 House Republicans to vote in favor of establishing a bipartisan commission into the Jan. 6 insurrection.

• The Illinois Republican released his message on the same day that a few hundred pro-Trump demonstrators protested outside the fenced-off U.S. Capitol in a "Justice for J6" rally.

What he's saying: "The future of the party and politics in this country doesn't rest on the 10 of us, it rests on the courage of the 180 others who have been silent so far," Kinzinger said in the video statement, referring to the January impeachment vote.

• "So many GOP colleagues watched from the sidelines lacking courage to speak out while privately hoping for change," he said.
• "When we all publicly take sides, then we can answer the question once and for all whose party is this," he added.
