Donald Trump has taken a swipe at First Lady Michelle Obama, accusing her of attacking Hillary Clinton during the 2008 primaries.
Mrs Obama is shown by polls as being far more popular than her husband or the two presidential nominees, and for much of the campaign Mr Trump has avoided directly challenging her.
But at a rally in North Carolina on Friday, the Republican nominee said that "all she wants to do is campaign" before accusing her of attacking Mrs Clinton.
He said Mrs Obama had said if you "can't run your own house," you can't run the White House, which Mr Trump said was aimed at the Clintons.
Mr Trump said: "We have a bunch of babies running our country folks. We have a bunch of losers.
"They're losers, they're babies, we have a president - all he wants to do is campaign, his wife, all she wants to do is campaign, and I see how much his wife likes Hillary.
"But wasn't she the one who originally started the statement, 'if you can't take care of your home...you can't take care of the White House or the country'."
Mrs Obama did make the comment but she and her husband denied it referred to the Clintons.
Last week, Mrs Obama launched a stinging attack on Mr Trump's "disgraceful" behaviour towards women, saying: "I can't believe that I'm saying that a candidate for president of the United States has bragged about sexually assaulting women."
