This week, Sen. Mark Warner (D-Va.) said that he believes the U.S. military could serve as a constraint on President Donald Trump’s administration, arguing that senior uniformed leaders remain primarily loyal to the Constitution rather than any individual political figure.

Speaking during an appearance on “MS NOW” Wednesday morning, Warner previewed questions he said he plans to ask U.S. Navy Adm. Frank M. Bradley when Bradley testifies Thursday before the Senate Intelligence Committee. Warner serves as the committee’s vice chair.

Warner said his questions will focus in part on concerns surrounding Defense Secretary Pete Hegseth and the administration’s recent military actions, including strikes in the Caribbean. Warner said he trusts Bradley, but raised doubts about Hegseth’s public statements.

“Remember, this is an administration that has treated the uniformed military with unprecedented disrespect when they were all brought to get a pep rally in front of Hegseth and Trump,” Warner said. “This is an administration that’s fired uniform generals from the head of the NSA, the head of the Defense Intelligence Agency.”

He added: “And I think in many ways, the uniformed military may help save us from this president and his lame people like Hegseth, because I think their commitment is to the Constitution and obviously not to Trump. And I expect Bradley to adhere to that.”

Warner’s comments follow similar remarks from other Democrats who have suggested service members could resist unlawful directives. Earlier this year, six Democratic lawmakers urged members of the military to resist “illegal” orders.

Rep. Eric Swalwell (D-Calif.) made a related argument in an interview last month with Don Lemon, saying he has spoken with service members who view their oath as a safeguard.

“What gives me hope, and I talk to service members all the time. They tell me that I don’t appreciate enough and the public doesn’t appreciate enough that while Congress is not a check on the president anymore, and the judiciary at the Supreme Court is hardly a check, military members have told me, ‘We can be a check,’” Swalwell said.

He continued: “They’re essentially saying, ‘We’re not going to betray our oath to the Constitution because this guy tells us to.’ While it’s not codified that way — they’re not a branch of government on their own— their honor and integrity might just save us.”

Former President Barack Obama also addressed the issue Monday, saying he has seen signs of “resistance” within the military to what he described as politicization, while adding he does not believe that politicization has fully taken hold.

“I would not expect the politicization of the Justice Department or our military,” Obama said. “And I don’t think that’s happened. I think there’s been resistance, particularly in the military, to that, but the degree to which that has been encouraged, you know, that used to be something that I would lecture other countries not to do.”
