The Exit Nobody Mourned
Kristi Noem is out at the Department of Homeland Security after a tenure that managed to unite Democrats and Republicans in one rare bipartisan consensus: good riddance. President Trump announced Thursday he's replacing her with Sen. Markwayne Mullin (R-Okla.), making Noem the first Cabinet secretary fired in his second term. Markets saw it coming — Kalshi traders pushed the odds of her ouster to 95% before the official announcement dropped.
The final straw? A $220 million advertising campaign featuring Noem on horseback in a cowboy hat, promoting Trump's mass deportation agenda. Sen. John Kennedy (R-La.) grilled her about the spend during a congressional hearing in early March, questioning how it squared with her "concern for [government] waste." Noem claimed Trump had "tasked me with getting the message out," but hours before her firing, Trump told reporters he "never knew" he'd blessed the campaign. Kennedy was more direct: the president was "not a happy cowboy."
A Greatest Hits of Controversies
The ad campaign was just the capstone. Noem came under fire for calling Alex Pretti — a protester shot and killed by federal immigration agents in Minnesota — someone who wanted to "kill" agents and "committed an act of domestic terrorism." She claimed he was "brandishing" his weapon. Bystander videos showed Pretti never reached for his gun and had been disarmed before he was shot. The incendiary and misleading rhetoric set off a blame game within the administration. Long delays in FEMA assistance after Hurricane Helene also brought bipartisan complaints, particularly from North Carolina Republicans.
Senate Republicans Line Up Behind Mullin
Senate Majority Leader John Thune (R-S.D.) said Mullin is "pretty well vetted around here, so hopefully we can get the process going" for a quick confirmation. Sen. Thom Tillis (R-N.C.) praised Mullin as someone who would "restore competence" to DHS. Even Sen. John Fetterman (D-Pa.), who has bucked his party before, said he'll vote to confirm Mullin. As @GaetenD noted on X, traders are now eyeing new markets: "How many votes will the next DHS secretary get? When will he be confirmed? Who will be Mullin's replacement in the Senate?"
But there's tension beneath the celebration. Mullin has "serious beef" with Sen. Rand Paul (R-Ky.), chair of the Committee on Homeland Security & Governmental Affairs, which will handle his nomination. Mullin called Paul "a freaking snake" at a Tulsa event last month, adding he "understand[s] completely why his neighbor did what he did" — an apparent reference to the 2017 assault on Paul. Still, with only a simple majority needed, Mullin's confirmation looks like a foregone conclusion. Senate Minority Leader Chuck Schumer (D-N.Y.) made clear Democrats won't unlock funding for DHS regardless: "This is not an issue of personnel. This is an issue of policy."
What to Watch
Noem lands in a new role as special envoy for "The Shield of the Americas," a security initiative Trump plans to announce Saturday. Oklahoma Gov. Kevin Stitt will appoint Mullin's Senate replacement, with Reps. Stephanie Bice and Kevin Hern already eyeing runs for the seat ahead of the midterms. The real question for traders: whether Mullin can execute Trump's mass deportation agenda without the bipartisan backlash that sank Noem — or whether personnel changes just mask deeper policy problems at DHS.
