[Jeanine Herbst]

In Washington, I'm Jeanine Herbst. Iran says President Trump's decision to extend a ceasefire with Tehran indefinitely at Pakistan's request means nothing on X. Mahdi Mohammady, an advisor to the speaker of the Parliament, says, quote, the losing side can't dictate terms. And President Trump says the US Blockade in the strait continues. President Trump's pick to head the Federal Reserve, Kevin Warsh was on Capitol Hill before a Senate Banking committee today. NPR Scott Horsley has more.

[Scott Horsley]

The Republicans on the Banking Committee were mostly supportive of this nomination, with the exception of Thom Tillis. The North Carolina senator is really the only thing standing in the way of Worsh being confirmed. And Tillis objection has nothing to do with Warsh himself. It's all about the Justice Department launching a criminal investigation of cost overruns on the Fed's headquarters renovation.

[Thom Tillis]

If we put everybody in prison in federal government that had had a budget go over, we'd have to reserve an area roughly the size of Texas for a penal colony.

[Scott Horsley]

Tillis thinks the investigation is just another way for the administration to put pressure on the Fed to cut interest rates, and he has vowed to hold up Warsh's confirmation until that probe is put to bed.

[Jeanine Herbst]

NPR Scott Horsley reporting. President Trump says the AI company Anthropic is, quote, shaping up signaling a possible reversal in the administration's battle with the company over the military's use of AI.

[John Ruich]

NPR's John Ruich has more in an interview with CNBC. Trump says it's possible there will be a deal that allows Anthropic's AI models to be used by the Pentagon. This comes in the wake of a high profile spat between the AI company and the administration. Anthropic does not want Claude to be used in autonomous weapons or for mass surveillance of Americans. The Pentagon says it's not up to companies to decide how the military uses their products. It blacklisted Anthropic as a supply chain risk, and Trump ordered federal agencies to stop using its technology. A judge in California blocked the ban, saying the government was apparently trying to punish the company. Anthropic's CEO, Dario Amadei, visited the White House last week and Trump told CNBC they had some good talks. John Ruich, NPR News.

[Jeanine Herbst]

The Trump administration says it's reviewing possible relief options for Spirit Airlines. NPR's Joel Rose reports.

[Joel Rose]

The Department of Transportation says it is taking a look at Spirit Airlines at the request of President Trump. In an interview with cnbc, Trump said Spirit's in trouble and that maybe the federal government should help, while also calling for another buyer to step in. Spirit filed for bankruptcy protection in August for the second time in less than a year. Now soaring fuel costs tied to the Iran war are adding even more uncertainty about the carrier's ability to keep operating. Spirit is not the only airline that's struggling with high fuel costs. A trade association for low cost carriers sent a letter to Congress last week asking for temporary tax relief. Joel Rose, NPR News, Washington.

U.S. futures contracts are trading higher at this hour. You're listening to NPR News. Congresswoman Sheila Cerfilis McCormick, a Democrat from Florida, resigned her seat today, effective immediately. This just before a hearing was set to start on whether she should be expelled for 25 violations of House rules and ethics standards, including breaking campaign finance laws and facing federal charges of stealing 5 million doll in federal Covid relief funds and using some of that on her 2021 campaign. She calls the committee's process a witch hunt. Scientists using instruments on NASA's Curiosity rover report they found organic molecules never before seen on Mars. As Joe Pelko reports, the discovery could help determine whether Mars could once have harbored life.

[Joe Palka]

Today, Mars is a dry, inhospitable place, not likely to harbor living organisms. But 3 billion years ago, researchers say the planet was wet and warmer, a place some kind of microbial life could have existed. They hope to find evidence for that hypothesis in rocks on Mars that have been on the planet since those warmer, wetter days. The new results, published in the journal Nature Communications, come from a rock sample the Rover collected in 2020. The sample was analyzed using the rover's onboard chem lab. It then took scientists on Earth years to analyze and understand the analysis. The Curiosity rover landed on Mars in 2013 with the goal of making just this kind of finding. For NPR News, I'm Joe Palka.
