Today in One Sentence. Trump fired Homeland Security Secretary Kristi Noem and replaced her with Sen. Markwayne Mullin Senate Democrats blocked a Republican bill to reopen the Department of Homeland Security for a third time the House rejected a bipartisan effort to force Trump to seek congressional approval for continued military action in Iran Trump said he wasn’t concerned about rising gasoline prices caused by the Iran war, saying “if they rise, they rise” two dozen Democratic-led states sued Trump to stop his new 10% global import tariffs and a Jan. 6 rioter pardoned by Trump was sentenced to life in prison for molesting two children.

1/ Trump fired Homeland Security Secretary Kristi Noem and replaced her with Sen. Markwayne Mullin, making Noem the first Cabinet secretary forced out in his second term. Mullin still needs Senate confirmation, but Trump said the change takes effect March 31 and called him a “MAGA Warrior” who would make a “spectacular Secretary of Homeland Security.” Trump added that Noem would become a special envoy for the “our new Security Initiative in the Western Hemisphere.” The move followed Noem’s claim that Trump had approved a roughly $200 million DHS ad campaign that prominently featured her, a claim Trump and White House officials contradicted. It also came after criticism of her handling of the Minneapolis immigration operations, where federal agents killed U.S. citizens Renee Good and Alex Pretti, who Noem labeled “domestic terrorists.” (Wall Street Journal / New York Times / Politico / Washington Post / NPR / NBC News / Bloomberg / ABC News / CNN)

2/ Senate Democrats blocked a Republican bill to reopen the Department of Homeland Security for a third time, saying Noem’s removal “changes nothing” because “the problems at this agency transcend any one person.” The Senate vote was 51-45, short of the 60 needed to advance. Democrats want binding limits on ICE and Border Patrol tactics, including identification, warrant, mask, and use-of-force rules, while Republicans say they’ve offered reforms and accused Democrats of refusing a deal. The standoff leaves the DHS shutdown on track to enter a fourth week. (New York Times / CNBC / The Hill / Axios / Associated Press / Politico / Washington Post)

3/ The House rejected a bipartisan effort to force Trump to seek congressional approval for continued military action in Iran, voting 219-212 to block consideration of the measure. The resolution, led by Rep. Thomas Massie and co-sponsored by Rep. Ro Khanna, would have required Trump to end offensive operations. Massie said the War Powers Resolution lets a president use force without Congress only in narrow cases, including a declaration of war, specific statutory approval, or a national emergency caused by an attack on the United States. “None of those conditions exist today,” he said. The vote came a day after the Senate blocked a similar measure, effectively signaling that Congress will not restrain Trump’s war powers on Iran.

4/ Trump said he wasn’t concerned about rising gasoline prices caused by the Iran war, saying “if they rise, they rise.” He called the U.S. military operation in Iran is “far more important than having gasoline prices go up a little bit,” claiming that “They’ll drop very rapidly when this is over.” That came as the national average gas price rose 27 cents in the last week to $3.25 a gallon. Meanwhile, Trump’s chief of staff, Susie Wiles, warned that failing to respond to higher fuel costs would be “catastrophic” for Republicans, while aides were “looking under every rock” for ways to lower prices. Two energy industry executives familiar with the conversations inside the White House said Energy Secretary Chris Wright and other advisers “are getting screamed at to find some good news” on bringing down prices. “Folks are scrambling for announcements and messaging to counter the narrative” of rising prices.(Politico / Bloomberg / Reuters / New York Times / The Hill / CNBC)

5/ Two dozen Democratic-led states sued Trump to stop his new 10% global import tariffs, arguing that Trump was trying to “sidestep” the Supreme Court’s decision to strike down most of his tariffs. After the ruling, Trump invoked Section 122 of the Trade Act of 1974, which allows tariffs of up to 15% for 150 days to address “fundamental international payments problems.” The states argued that the U.S. trade deficit doesn’t meet that standard, asked the court to block the tariffs, and refund any duties already collected.

6/ A Jan. 6 rioter pardoned by Trump was sentenced to life in prison for molesting two children. Andrew Paul Johnson was found guilty on 5 state charges in Florida, including molesting a child under 12, molesting another under 16, lewd exhibition, and sending harmful material to a minor. He tried to keep one victim quiet by promising money he expected from the federal government after Trump’s pardon, and investigators found explicit messages he sent on Discord.
