In the midst of a prison death scandal riling his office, Milwaukee County Sheriff David Clarke announced today that he will be joining the Trump administration as a Department of Homeland Security assistant secretary.

Having had four people, including a baby, recently die at his jail didn’t stop the Trump administration from courting Clarke, whose name was first floated for an administration job quickly after Donald Trump’s election as president. Last month, Politico revealed that Clarke was preparing to join Homeland Security.

The Wisconsin sheriff became a conservative icon after making a string of wild and outlandish statements. He aligned himself with Trump and made regular appearances on Fox News, further elevating his platform.

Clarke has “compared Beyonce to a Ku Klux Klan member, called for the Great Seal of the United States to feature a semi-automatic rifle, and repeatedly demanded a literal uprising against the government in protest of President Obama’s gun violence proposals, potential election rigging and marriage equality.” He once tweeted that anti-Trump protests “must be quelled.”

That’s far from all.

“Clarke suggested that any person who posts pro-terrorist sentiments on social media be arrested, deprived of the constitutional protection against unlawful imprisonment (known as habeas corpus), and sent to Guantanamo Bay indefinitely,” Pema Levy of Mother Jones writes. “He estimated the number of people who could be imprisoned under his proposal could reach 1 million. Presumably, this would include American citizens.”

Clarke once said that when he hears “people say we need to reach across the aisle and work with the Democrats, you know what I say? The only reason I’ll be reaching across the aisle is to grab one of them by the throat.”

As we have also reported, Clarke has developed ties with radical anti-government groups; used incendiary language to describe his perceived enemies like the Black Lives Matter movement, which he linked to ISIS, and Barack Obama; and attacked victims of police violence:
