A Texas police officer resigned Tuesday after a video emerged of him slamming an unarmed teenager to the ground at a pool party.

The video shows Cpl. Eric Casebolt pin a bikini-clad girl to the ground, then draw his gun on other teens.

McKinney Police Chief Greg Conley said that Casebolt was "out of control" and confirmed that he resigned from the force earlier in the day. 

"The actions of Casebolt, as seen on the video of the disturbance at the community pool, are indefensible," Conley said.

On "The Kelly File" tonight, Milwaukee County Sheriff David Clarke said that it is "highly unlikely" that Casebolt will be able to get another law enforcement job.

"What I saw tactically I had a huge problem with some of the things that officer did," Clarke said. "He lost his head. He didn't keep his wits about him."

Clarke told Megyn Kelly that he doesn't think Casebolt will face any criminal charges. 

Kelly also asked Clarke what he thinks about the recent comments made on MSNBC by Rev. Ronald Wright, executive director of Justice Seekers Texas. 

"We’re setting the stage for a terrorist attack in this country. And the group is not going to be ISIS, it’s going to be USIS, us against these unjust law officers and people who continue to allow racism to grow into this city," Wright said.

Clarke said that Wright's group should be named "revenge seekers" instead. 

"The rhetoric coming out of there ... is over-the-top and doesn't serve anything," Clarke added.
