Will Trump's administration picks impact House control?
While control of the House has not yet been projected by ABC News, Republicans are inching toward maintaining their slim majority.
But already, Trump has picked several lawmakers to serve in his administration: Rep. Elise Stefanik for United Nations ambassador and Rep. Mike Waltz for national security adviser.
Speaker Mike Johnson, asked about the issue on Tuesday, said he's spoken to Trump about it several times.
"We have a really talented Republican Congress ... Many of them can serve in important positions in the new administration. But President Trump fully understands, appreciates the math here and it's just a numbers game," Johnson said. "You know, we believe we're going to have a larger majority than we had last time."
The speaker added: "I don't expect that we will have more members leaving, but I’ll leave that up to him."
