Donald Trump failing to draw the crowds he's grown used to Friday night. The presumptive Republican presidential nominee kicking off his first general election swing in Richmond, Virginia. Trump taking the opportunity to attack President Barack Obama's endorsement of Trump's Democratic challenger, Hillary Clinton.>> And I hear he's gonna take a lot of time during our time, when he's supposed to be looking at trade, and the military, and all of these things.
And he's gonna campaign for crooked Hillary. And you know what? That's okay. That's okay. Cuz if he does that, we're allowed to say things about him that normally we wouldn't bring up. Okay?>> Trump reserved some of his most scathing commentary for another person who's now endorsed Clinton, Massachusetts Senator Elizabeth Warren.
>> But this Elizabeth Warren, I call her goofy. Elisabeth Warren, she's one of the worst senators in the entire United States Senate. She's gotten practically nothing done, practically nothing passed. And I hope she's gonna be chosen by Hillary, would that be great, I would love it.>> More than 100 people protested outside Trump's appearance in Richmond, with police saying one person was charged with disorderly conduct.
