Lewandowski “no longer has a role at DHS,” the DHS spokesman said, without providing further details.

Lewandowski had been an unpaid adviser to Noem. He previously served as president Donald Trump’s campaign manager in the 2016 election.

Lewandowski did not respond to a request for comment.

The department’s confirmation of his departure was first reported by Politico.

Trump fired Noem earlier this month, saying she ​would become special envoy to a ​new “Shield ⁠of the Americas” initiative to promote his security policies in the Western Hemisphere. ⁠

Noem ​has since been replaced as the head of DHS by ​former US Senator Markwayne Mullin, whom the Senate confirmed on Tuesday.

The close relationship between Lewandowski and Noem drew scrutiny.

At a congressional hearing earlier this month, a Democratic lawmaker asked Noem directly whether she had a sexual relationship with Lewandowski – a question Noem dismissed ⁠as “tabloid garbage”.

Lewandowski appeared with Noem in photos released on Wednesday by the US embassy in Guyana, which showed him by her side in meetings with Guyana’s ​president Irfaan Ali.

Noem, in her new role, reports to deputy state secretary Christopher Landau.

A state department official earlier this week declined to explain to Reuters why Lewandowski ​was on the trip with Noem but said he would not be joining the department in any capacity.
