Sheriff David Clarke's no nonsense, tell-it-like-it-is approach has transformed the Milwaukee County sheriff into a conservative icon. Beloved by Trump supporters, the sheriff was even invited to speak at Donald Trump's 'DeploraBall' over inaugural weekend. And now the tough-talking lawman has turned his attention to Facebook founder and CEO Mark Zuckerberg, calling out the tech titan over his stance on Trump's ban on refugees.

Saturday morning, on the "Fox & Friends Weekend" show, Sheriff Clarke addressed the critics of President Trump's recent executive order, which temporarily restricts refugees from certain countries from entering the United States.

Clarke had one critic in particular in his crosshairs -- Mark Zuckerberg.

Sheriff Clarke doesn't like being lectured

Clarke declared that he was tired of 'one-percenters' like Zuckerberg lecturing the rest of America about borders and immigration. "I know who I am and most Americans know who they are. We are a sovereign nation," said Clarke. "If you’re going to be a sovereign nation, you have to have borders and you have to protect those borders." Clarke then claimed that Zuckerberg had no idea who is entering the U.S. and what it takes to vet those individuals, and pointed out that Zuckerberg's own home in Hawaii was protected by a wall.

Clarke didn't mince words when asked about the Syrian refugee crisis.

"I’m tired of all the crocodile tears about the kids -- the poor kids coming,” he added. Sheriff Clarke alleged that a significant portion of Syrian refugees were not women and children, but grown men of fighting age who should be back in their homeland trying to save their country.

Zuckerberg's statement

Clarke's criticism of Zuckerberg stems from comments the Facebook founder made on Friday after President Trump signed several executive orders, including an order to start the process of building a wall along the U.S.-Mexico border and another order establishing a temporary ban on refugee entry.

In Zuckerberg's statement, which was posted on his official Facebook page, the social media mogul said, “The United States is a nation of immigrants, and we should be proud of that. We should also keep our doors open to refugees and those who need help. That’s who we are."
