GOP Rep. Roy of Texas said he is running to challenge Rep. Stefanik in her bid to become the next Republican conference chair. An election is expected to begin at 8:30 a.m. ET Friday for House Republicans to select their new No. 3, where Stefanik is widely expected to prevail. Roy said that while he respects Stefanik, he has a concern at the pace at which the vote to fill the post is happening.
