Dems put Noem on notice

President Trump fired Homeland Security Secretary Kristi Noem in March, but Democrats aren't finished with her. Why it matters: Armed with commanding House and Senate majorities, they're preparing to haul the architects of Trump's mass deportation agenda before Congress to answer for their actions. "Noem, Markwayne, Miller, Homan, Bovino, what's up? Clear your schedule," Rep. Delia Ramirez (D-Ill.), a member of the House Homeland Security Committee, warned on X. She was referencing current DHS Secretary Markwayne Mullin (who replaced Noem), White House Chief of Staff Stephen Miller, Border Czar Tom Homan and former Border Patrol commander-at-large Gregory Bovino. Dems on the House Oversight Committee included former DHS Special Government Employee Corey Lewandowski in a list of people who should "lawyer up." Zoom in: Rep. Bennie Thompson, the top Democrat on the Homeland Security Committee, said in a letter to colleagues he'd prioritize investigating every death in DHS custody and during arrests. Thompson, who is running for committee chair and the subpoena power that comes with it, also plans to investigate alleged financial corruption at the agency and oversight of spending, particularly the gargantuan budget supplied by the One Big Beautiful Bill. "I called for Kristi Noem's impeachment in January, and she was gone by March. But the questions she refused to answer are still open," Thompson wrote. "Tom Homan and Stephen Miller would not appear [for a hearing] when we invited them this spring. In the majority, they will not have that choice," he wrote. Zoom out: Democratic leaders in both the House and Senate have a lengthy list of areas for oversight, according to sources familiar with their plans. That includes: The billions spent to expand ICE detention , including Alligator Alcatraz and a warehouse buying spree. Oversight agencies have been reviewing these purchases. Noem's purchase of luxury private jets that she claimed could be used for deportation flights.
