Harris 'will not be the first woman president' -Trump

"She kept laughing. I said, is there something wrong with her too? She will not be the first woman president. You can't let that happen," Trump said.

With eight days until the U.S. election, President Donald Trump on Monday wooed voters in Pennsylvania, a battleground state he won in 2016 and is crucial to his chances of defeating Democratic challenger Joe Biden and winning a second term.

More than 60 million Americans already have cast ballots ahead of the Nov. 3 election in a record-breaking pace that could lead to the highest U.S. voter turnout by percentage in more than a century.
