Colorado representative Ken Buck announced Tuesday that he will resign from Congress next week rather than complete his current term.

Buck, a member of the Freedom Caucus, announced his intent to retire from Congress in November. He doesn't seem to have given anyone a heads-up about his plans.

Speaking to reporters shortly after the news broke, Johnson suggested he did not get a heads-up from Buck.

"I was surprised by Ken’s announcement. I’m looking forward to talking with him about that," the speaker said.

Other GOP colleagues said they were taken aback by Buck's decision. “Very surprising, very disturbing, very alarming, very concerning," said Rep. Pat Fallon, R-Texas.

His departure reduces the House GOP majority to 218-213, meaning that Speaker Johnson has a total of two votes he can lose before depending upon the kindness of Hakeem Jeffries to pass legislation.
