Bukaty/APCOLUMBIA, S.C. — Nikki Haley on Saturday questioned whether Donald Trump is mentally capable of serving as president again after he repeatedly seemed to confuse her with former U.S. House Speaker Nancy Pelosi in a campaign speech. "They're saying he got confused, that he was talking about something else, he's talking about Nancy Pelosi," Haley said on Saturday. Speaking at a Bloomberg News forum on Saturday in Manchester, Haley campaign manager Betsy Ankney referenced Haley's remarks and said Trump "made a pretty apparent gaffe last night." It's Nikki and Nancy," Trump campaign senior adviser Chris LaCivita said to reporters Saturday night. At his rally Saturday night in Manchester, Trump said that he took a cognitive test and "aced it."
