Massachusetts Sen. Elizabeth Warren ripped Donald Trump on Friday after the Republican nominee conceded that President Barack Obama was born in the United States, following more than half a decade of leaving the president's citizenship as an open question.

"Let's be clear: @realDonaldTrump just admitted that he peddled fake conspiracy theories to attack the integrity of @POTUS," tweeted Warren, who has been a fierce opponent of Trump on the trail and on Twitter for months.
