President Trump brands O'Rourke on first day of campaign — and Beto does not like it one bit

President Donald Trump mocked Beto O'Rourke on Thursday when he was asked to comment on the start of his presidential campaign, and O'Rourke responded timidly soon after.

"Well, I think he's got a lot of hand movement, I've never seen so much hand movement. I said, is he crazy or is that just the way he acts?" the president said to reporters.

"So I've never seen hand movement, I watched him a little while this morning doing I assume it was kind of a news conference, and I've actually never seen anything quite like it," he added.

"Study it, I'm sure you'll agree!" he concluded.

Here's the video of Trump's reaction to Beto:

O'Rourke was asked later about Trump's insult, and he laughed it off during a campaign stop in Burlington, Iowa.

"Oh, did he? I have nothing to say to that," O'Rourke responded.

"I think people want us to rise above the pettiness, the smallness," he added, "they want us to be big, bold, ambitious for this country. That's what I'm focused on and that's what I see here today in Burlington."

O'Rourke was defeated in an uphill battle to unseat Sen. Ted Cruz (R-Texas), but got close enough to excite his supporters and propel him to a presidential campaign. He was formerly a member of the U.S. House of Representatives.

Trump was apparently referring to video of O'Rourke at a campaign stop in Keokuk, Iowa.
