Donald Trump appears to kick out crying baby at rally in Ashburn, Virginia

ASHBURN, Virginia -- First responders are calling it the most catastrophic incident they've seen in decades. Rescue efforts lasted for hours as dozens of injured passengers were shuttled to local hospitals.

Apparently, there was a crying baby in the crowd. At first, the Republican presidential nominee said, "Don't worry about that baby. I love babies."

Then he has second thoughts.

"Actually, I was only kidding, you can get the baby out of here ... I think she really believed me that I love having a baby crying while I'm speaking."

Trump then seemed to suggest that he was joking and that the baby could stay. The child soon stopped crying.
