Maryland Gov. Larry Hogan (R) told reporters Wednesday that he wouldn’t be voting for Donald Trump come November, The Washington Post reported.

“No, I don’t plan to,” Hogan said when asked if he’d vote for Trump. “I guess when I get behind the curtain I’ll have to figure it out. Maybe write someone in. I’m not sure.”

Hogan had endorsed now-Trump surrogate New Jersey Gov. Chris Christie (R) for the presidency, but later said he wouldn’t endorse anyone in the 2016 race once Trump became the presumptive nominee.

Republicans are divided on how they’ll support their party’s nominee, given Trump’s rhetoric particularly after he suggested that he would broaden his ban on Muslims to include persons from countries with “a proven history of terrorism” against the United States and its allies.
