Defense secretary had contentious hearing in which he sparred with Democratic senators over various issues

The US defense secretary, Pete Hegseth, suggested on Wednesday that he would not obey a federal court ruling against the deployments of national guard troops and US marines to Los Angeles, the latest example of the Trump administration’s willingness to ignore judges it disagrees with.

The comments before the Senate armed services committee come as Donald Trump faces dozen of lawsuits over his policies, which his administration has responded to by avoiding compliance with orders it dislikes. In response, Democrats have claimed that Trump is sending the country into a constitutional crisis.

California has sued over Trump’s deployment of national guard troops to Los Angeles, and, last week, a federal judge ruled that control of soldiers should return to California’s Democratic governor, Gavin Newsom. An appeals court stayed that ruling and, in arguments on Tuesday, sounded ready to keep the soldiers under Donald Trump’s authority.

“I don’t believe district courts should be determining national security policy. When it goes to the supreme court, we’ll see,” Hegseth told the Democratic senator Mazie Hirono. Facing similar questions from another Democrat, Elizabeth Warren, he said: “If the supreme court rules on a topic, we will abide by that.”
