White House press secretary Sarah Huckabee Sanders refused to comment on the reports during her press briefing on Monday.

"We haven't had that conversation about Sen. Corker's plans. As always, I can't weigh in on the specifics of the potential of a race but I would have to talk to the president before making a comment," she said.
