Milwaukee County Sheriff David Clarke said on "The Kelly File" tonight that President Obama has an obligation to speak out against the anti-police rhetoric that is coming from groups like Black Lives Matter.

Clarke pointed out that Obama's comments following the death of Michael Brown in Ferguson breathed life into the Black Lives Matter movement.

"He's got an obligation to come out now and walk some of this back, remind people of the important role that law enforcement officers play, and no longer will this anti-cop madness, this anti-cop slime, be tolerated," Clarke said.

"We know the political class, including the president, have turned their back on us, and we're kind of out here alone now," Clarke added.

He said that even though many law enforcement officers don't feel supported by the president or the attorney general, they are still going to serve their communities.

Clarke pointed to the tragic death of Fox Lake Police Department Lt. Joe Gliniewicz, who was shot in the line of duty just 30 days before his retirement.
