Tracy Mumford: From the New York Times, it's the headlines. I'm Tracy Mumford. Today's Wednesday, April 1st. Here's what we're covering.

Reporter: I just landed in Houston. This is where NASA's mission control is for its first moon mission with humans on board in more than 50 years. My colleague Katrina Miller is on the ground in Texas to track the launch of the Artemis 2 mission. It's currently scheduled for tonight, barring bad weather or other complications. The capsule, which will be carried into space on a 300 plus foot rocket, is set to travel around the moon, taking the astronauts farther from the Earth than anyone has been since 1972. Four astronauts are flying aboard the spacecraft. They will launch from Kennedy Space Center in Florida. They will loop around the Earth and then do a trans lunar injection burn toward the moon. Loop around the far side of the moon and then around day 10 they will splash down off the coast of California. The crew will get to see and photograph the far side of the moon, the part that we never see from Earth with their own eyes. But ultimately, Artemis 2 is a test flight in a series of missions by NASA to return humans to the surface of the moon and then hopefully eventually someday travel beyond it. The US has found itself in a space race once again as China has said it's planning to try and land astronauts on the moon by 2030. NASA, for its part, is hoping to pull that off by 2028 if this Artemis mission and the next few go according to plan. We're finishing the job and I think within maybe two weeks, maybe a couple of days longer to do the job.

Reporter: In the Oval Office yesterday, President Trump said the US will end its military campaign in Iran in the next few weeks. And he promised to address the nation tonight with what the White House says will be an important update on the war.

President Trump: I had one goal. They will have no nuclear weapon. And that goal has been attained. They will not have.

Reporter: Trump declared that the US has completely eliminated any nuclear threat from Iran, a claim that is not backed up by any evidence. Iran still has nearly a,000 pounds of highly enriched uranium, which could be used to build a nuclear weapon. Also, it's unclear whether decimating Iran's nuclear program is even a true focus of the war. While Trump talked it up when he announced the operation, lately his top officials have been narrowing the stated goals.

President Trump: I hear a lot of talk about we don't know what the clear objectives are. Here they are. You should write them down.

Reporter: This week, Secretary of State Marco Rubio gave an updated list of what he said were the administration's aims in Iran.

Marco Rubio: Number one, the destruction of their air force. Number two, the destruction of their navy. Number three, the severe diminishing of their missile launching capability. And number four, the destruction of their factory. So they can't make more missiles. and more drones to threaten us in the future. All of this.

Reporter: Rubio's list, which didn't address the uranium, seemed to be an attempt to give the US an offramp from the conflict, effectively lowering the bar so that Trump can declare victory. Rubio also didn't mention anything about regime change, another claim Trump has been making. Iran's hardline government is still running the country. Yesterday, the stock market surged amid hopes of the war ending soon. Trump's address is scheduled for 9:00 p.m. Eastern tonight.

Christina Goldbomb: Meanwhile, in Lebanon, Israel has issued these sweeping evacuation warnings for much of southern Lebanon, about 10% of the country. But our reporting has shown that in private, they're giving a more targeted message. Christina Goldbomb covers Lebanon for the Times, and she's found that Israel isn't telling everyone to leave from the areas it's targeting. Israeli military officials have been calling several Christian and Drews communities and assuring them that they can stay and that they're actually only focused on driving Shiites out. Shiite Muslims are from the same sect as Hezbollah, the Iranbacked militant group Israel's fighting in Lebanon. I went to Calca, a Marinite Christian town near the border with Israel. It's a town that had taken in around two dozen Shia families who had been displaced from their border village. When we were there, we were talking to the deputy mayor who was telling us how other villages nearby had gotten these calls from Israeli military officials telling them that if they had Shia living in their towns, they needed to tell them to leave, otherwise their town would not be safe from Israeli bombardment. And she was telling us how she had gone to these displaced Shia families, told them to prepare themselves, that if they got a call telling them to expel their Shia residents, the town would do so. And later that day, the mayor of the town got the call from Israeli military officials and within 24 hours, they had put those displaced Shia families on buses heading north out from Koba. Having spoken to Shia residents, to municipal leaders, to other local leaders who've been receiving these calls, it's become clear to them that Israel is not only intent on changing the geographic map of southern Lebanon, but also the demographic one. The message that they understand is that Christians and Drews will be allowed to stay. And now Shia Lebanese who have fled the south are increasingly concerned that they may never be able to return to their homes.

Reporter: Now back to Washington for a few quick updates. At the Supreme Court yesterday, the justices handed conservatives a major win in a case about so-called conversion therapy for LGBTQ minors. In an 8:1 decision, the court threw out a Colorado law that banned mental health professionals from using talk therapy to try and change kids sexual orientation or gender identity. The justices said the law was a quote egregious assault on free speech and the First Amendment. The court's decision has implications for more than 20 other states that have similar laws barring conversion therapy, which critics and major medical organizations say is ineffective and potentially dangerous for young people. Also,

President Trump: so we're going to be signing an executive order. It's I believe it's foolproof and maybe it'll be tested, maybe it won't. I think it's very.

Reporter: President Trump is stepping up his efforts to take more federal control over elections, signing an executive order yesterday that would create a national list of eligible voters and restrict mail-in ballots. It's part of his ongoing effort to promote his false claims of widespread voter fraud, and it could violate the Constitution. The president has no explicit authority to manage elections, a power the Constitution gives to states and Congress. Trump's previous executive orders around elections, including one requiring proof of citizenship to vote, have largely been blocked by the courts.

Reporter: And last update, basically, he's saying, "I need congressional approval." And he's so wrong. President Trump is vowing to fight an order from a federal judge that's temporarily blocked construction of his ballroom. In the decision, which was handed down yesterday, the judge wrote that work on the massive White House expansion, has to stop, quote, "unless and until Congress blesses this project." The National Trust for Historic Preservation, which has been leading the court battle against the ballroom, has raised concerns about the breakneck speed at which it's moved forward and how it's being paid for. Hearings about it have been going on for months, and the judge appeared to lose patience with the government's lawyer, asking him at one point to quote, "be serious." and back off claims that the $400 million undertaking is comparable to minor renovations that previous presidents have done, like adding a tennis court.

Reporter: And finally, every picture we get of a Congress man or woman vacationing in the next two weeks, we want those pictures. The Hollywood tabloid TMZ, which is known for sending paparazzi and tipsters after celebrities, is turning its sights on Congress.

Reporter: We got Ted Cruz leaving this morning. The site's founder, Harvey Leven, said that since lawmakers started jettting off on their spring recess last week without reaching a deal to reopen the Department of Homeland Security, he wants every picture people can send in of senators and representatives out there living it up and not funding the government. TMC has posted pictures of Republican Senator Lindsey Graham at Disney World and Democratic Representative Robert Garcia in Vegas.

Reporter: In response to their photos being posted, Graham said that his Florida trip was part of a meeting with administration officials. And Garcia said he was visiting his dad in Vegas.

Robert Garcia: Garcia posted online though, quote, "Actually, I don't mind what TMZ is doing here," saying he didn't think congressional leaders should have sent lawmakers home with no deal in place.

Tracy Mumford: Those are the headlines. One big story to watch this morning. The Supreme Court will hear arguments about President Trump's push to end birthright citizenship for many immigrants.
