Sen. Josh Hawley of Missouri announced his support for Sen. John Cornyn of Texas on Friday in the race to replace Senate GOP leader Mitch McConnell. At this point, this is the first public endorsement for Cornyn. Cornyn is running to succeed McConnell alongside Republican Sens. Rick Scott of Florida and John Thune of South Dakota. "I'm backing John Cornyn for majority leader," Hawley said in a statement. "In the last two years, nobody has done more to win back the majority than he has."
