Markwayne Mullin (R-OK) is described as Donald Trump’s pick to run the Department of Homeland Security and faced Senate consideration on Wednesday, March 18, 2026 (per the source article).
The article says Mullin has never served in any branch of the US armed forces but often speaks in interviews in ways that could be taken as personal combat experience.
Example cited: after US strikes on Iran, Mullin described the “smell” and “taste” of war, then awkwardly pivoted to describing what he implied Defense Secretary Pete Hegseth experienced.
The article says Axios reported Mullin privately hinted to colleagues about dangerous private security work in Middle East war zones before he ran for Congress in 2012 (the Guardian attributes this to Axios).
At a hearing, per the article, Mullin confirmed he had not traveled abroad before Congress except for vacation or mission work when questioned by Sen Gary Peters (D-MI).
In a radio interview cited, a host called Mullin “a veteran”; Mullin responded by claiming “special assignments outside of DoD” and said he “never wore the uniform,” while suggesting he worked alongside military contractors.
The article compiles earlier remarks tied to January 6, 2021, where Mullin suggested he’d faced comparable situations “overseas,” but declined to explain his background when asked on C‑SPAN.
The source reports Mullin’s office told the Washington Post that his pre-Congress “overseas” reference related to Christian mission work with troops returning to the US.
The story includes a separate anecdote from a 2015 Israel lawmaker trip (via Politico), presented as character-color rather than directly tied to the credential/war-experience question.
