Kristi Noem‘s cross-dressing husband might have been exposed by an undocumented immigrant seeking retribution over President Trump‘s Department of Homeland Security policies.

Here’s the deal … Axios White House reporter Marc Caputo posted on X Tuesday that he received a “weird” tip in February about Bryon Noem‘s secret gender bending impulses, which include photographing himself wearing huge fake breasts and pink spandex shorts.   

But, get this … Caputo says the tipster was “an immigrant sex worker” who was possibly in the country illegally, and “wanted to go public about Noem’s husband using her services online — it was vengeance for DHS’s immigration enforcement.”

In a second post, Caputo gave the Daily Mail props for verifying the claims made by the anonymous source to get the scoop and the pics of Bryon, which it published Tuesday.

According to the story, Bryon entered the bizarre fetish world of “bimbofication,” where adults use saline to enlarge fake breasts to become a Barbie doll-like character.

Bryon was living a secret double life, chatting online with fetish models while cross-dressing in numerous photos and claiming to be a big fan of “huge, huge ridiculous boobs” … according to Daily Mail.

As for Kristi Noem — President Trump’s Special Envoy for The Shield of the Americas — she says she was blindsided and devastated by the report.
