House GOP majority to shrink as top Rep. Mark Green plans exit

• Green said in a statement he was "offered an opportunity in the private sector that was too exciting to pass up."
• The Tennessee Republican said he'd resign after the House votes on a final version of the Trump budget bill.
• A spokesperson for Johnson declined to comment.

Flashback: Green said last year he would not run for reelection, but later reversed his decision.

• "Though I planned to retire at the end of the previous Congress, I stayed to ensure that President Trump's border security measures and priorities make it through Congress," Green said in his statement on Monday.
• He added: "By overseeing the border security portion of the reconciliation package, I have done that."

Zoom in: Green and Johnson met with Rep. Michael McCaul (R-Texas), a former Homeland Security Committee chair who most recently chaired the Foreign Affairs Committee, about taking over for Green, a source familiar with the matter told Axios.

• The plan would involve McCaul chairing the panel through 2026 to give candidates for the role time to campaign, the source said.

What to watch: Green's seat is solidly Republican and likely to stay in GOP hands.

• When he leaves, Republicans will be down to a 219-212 majority, which means they will only be able to lose three votes on any given party-line bill.
