Meet the Press moderator Chuck Todd revealed sources have told him at least one incumbent Republican Senator may publicly endorse Hillary Clinton for president if Trump cements his lead as the party’s presidential frontrunner.

“I heard real speculation today from very informed people that at least one Republican Senate incumbent if given the choice might publicly endorse Hillary Clinton,” Todd said on MSNBC’s coverage of Super Tuesday.

“An incumbent Senator is at least one that I’ve heard that could end up doing that, making that choice,” Todd said. “Not because they want to, but because they need to send that message, look there is a bunch ever them running for reelection in a lot of blue states.”
