COLUMBIA, S.C. — Nikki Haley said Wednesday that she will be voting for Donald Trump in the general election, encouraging the presumptive GOP nominee to work hard to win support from those who backed her in the primary. “I will be voting for Trump,” Haley, Trump’s former U.N. ambassador, said during an event at the Hudson Institute in Washington. But Haley also made it clear that she feels Trump has work to do to win over voters who supported her during the course of the primary campaign, and continue to cast votes for her in ongoing primary contests. “Having said that, I stand by what I said in my suspension speech,” Haley added.
