Trump's Mental Acuity Questioned After False Birther Claim and Pelosi Mix-up

Former President Donald Trump defends his recent mangling of GOP primary challenger Nikki Haley's birth name, echoing a false birther claim that she is not eligible to run for president because she wasn't born in the United States. Trump says he's just having "fun" with the nicknames he bestows, while his campaign denies racist undertones. Both Trump and Haley's campaigns are working to appeal to voters ahead of the New Hampshire GOP primary, with Trump's false birther claims being reminiscent of the conspiracy theories he once pushed against Barack Obama and Kamala Harris. Haley says Trump engages in name-calling because he feels "threatened" and that it doesn't bother her, while several former GOP presidential candidates declined to denounce Trump's comments.
