Former Maryland Governor Larry Hogan urged Republicans to support presidential candidate Nikki Haley, curbing speculation that he could run on a third-party ticket.

“It’s time for the party to get behind Nikki Haley,” Hogan said Sunday on CNN’s State of the Union, adding that Haley has “the strongest chance for us to put forth our best possible candidate for November.”

The comments toed the line of a full-fledged endorsement, putting political weight behind Haley on the eve of the Iowa caucus. The latest Iowa poll has Haley narrowly eclipsing Florida Governor Ron DeSantis as a distant second to former president Donald Trump.
