Milwaukee County Clerk George L. Christenson has confirmed that Milwaukee County Sheriff David Clark resigned Thursday afternoon, according to TMJ4. His resignation was received at 3:17 p.m.
The reason for his resignation is not immediately clear.
Clarke had recently been under consideration for a position with the Department of Homeland Security, but withdrew his name from consideration in June.
Even though Clarke is registered and elected as a Democrat, Clarke was a vocal supporter of Donald Trump during the 2016 campaign. He is a frequent guest of Fox News and was a speaker at the 2016 Republican National Convention.
Clarke was appointed sheriff by Governor Scott McCallum, and later elected to his first four-year term. He was re-elected in November 2006, 2010 and 2014.
Clarke has been a controversial figure at times and has faced backlash over his management of a Milwaukee County Jail, in which an inmate died of dehydration.
Clarke’s national profile rose a few years ago when he began making regular appearances on Fox News in late 2014 to talk about policing after the unrest in Ferguson, Missouri, following the police killing of Michael Brown
