Donald Trump: President Barack Obama 'Is the Founder of ISIS'

The GOP presidential candidate made the comments at a Florida rally.

Trump's declaration was met with chants of "Lock her up!" from rallygoers.

Trump referred to the president using his middle name, calling him Barack Hussein Obama — a move that's typically been employed by those who claim Obama is secretly a Muslim.

"And Hillary won't say it either," Trump continued. "She doesn't want to say it, 'cause she doesn't want to offend the president, because then bad things could happen to her if she offends the president. Bad things could happen to her. So she's afraid to say it. Hillary's afraid to say it. She did say that she would say it because of me, but she's afraid to say it. But we have a real problem with radical Islamic terror. It's what it is. It's terror."
