Milwaukee County Sheriff and staunch President Trump backer David Clarke Jr. — who visited Moscow in 2015 on an NRA-financed junket — said Wednesday that he will be joining the Department of Homeland Security as an assistant secretary.

But that was news to DHS, which said later that nothing was official.

“No such announcement with regard to the Office of Public Engagement has been made,” a spokesperson for the DHS told BuzzFeed News.

“The position mentioned is a Secretarial appointment. Such senior positions are announced by the Department when made official by the Secretary.”

Clarke made the claim on the Milwaukee radio station WISM.

“I will be leaving the position of sheriff to accept an appointment as an assistant secretary at the Department of Homeland Security,” Clarke said. “I’m both honored and humbled to be appointed to this position by Secretary [John] Kelly, working for the Trump administration.”

Clarke, a tough-on-crime African-American lawman who appeared on TV backing Trump frequently during the campaign, said the job would be in the department’s “office of Partnership and Programs.

But DHS has no such office, though there is an Office of Partnership and Engagement.

“I will be a liaison with state and local government with the private sector,” Clarke said. “And one that’s really near and dear to me, liaison with the state, local and tribal law enforcement.”

Clarke was slammed for travelling to Russia for the NRA in 2015, when he met with Dmitry Rogozin, a deputy to President Vladimir Putin — yet another Team Trump member with ties to the Kremlin.

Clarke also harshly criticized the Black Lives Matter protests as “subhuman behavior,” the website said.

Juliette Kayyem, who was assistant secretary for intergovernmental affairs at DHS under ex-President Obama, tweeted that she was “floored” that Clarke could would be taking her previous job.

“For those of you I’m just meeting, Clarke is taking my old position under Obama. I am floored. And feel for my career staff,” she wrote on Twitter.
