Two years after Congress wiped more than $100 billion in obligations off the U.S. Postal Service’s books, the mail service and its allies are pressing for help again, warning that the agency could face a financial crisis that affects home delivery without billions more.

The Supreme Court appeared deeply divided Tuesday over whether prosecutors improperly stretched federal law to charge hundreds of participants in the Jan. 6, 2021, attack on the Capitol, a decision that will impact those rioters and, potentially, Donald Trump’s election interference trial in D.C. The court’s ruling has the potential to unwind their convictions and sentences, most of which were well under 20 years, and upend the charges still pending for other defendants. Three Jan. 6 defendants have had their sentences reduced ahead of a decision by the Supreme Court. The court’s decision, expected by late June or early July, could also further delay Trump’s already stalled trial for allegedly trying to remain in power after his 2020 defeat. Two of the four charges he faces are based on the obstruction statute, and he could move to have those charges dismissed if the Supreme Court rules for the rioters.

NASA has announced a plan to bring pieces of Mars back to Earth. The mission is an ambitious attempt to secure pristine chunks of the Red Planet that might help scientists reveal whether it ever hosted life. But the future of the project has been uncertain since last fall, when an independent review board produced a dire report saying the mission needed a management overhaul amid probable cost overruns and delays. A 2020 report from the board had estimated sample return would cost $3.8 billion to $4.4 billion. Now the estimated cost over the lifetime of the mission is between $8.4 billion and $10.9 billion, with samples arriving on Earth in 2040

No jurors have been selected yet in former president Donald Trump’s hush money trial in New York. On Monday, nearly 100 potential jurors were brought into the courtroom. Half were promptly excused after saying they could not be impartial. The questioning process began for 10 of the people remaining in the jury pool and will continue Tuesday.

Iran launched its much-anticipated attack on Israel on Saturday. More than 100 ballistic missiles were fired, senior U.S. officials said, complemented by about 30 cruise missiles and more than 150 explosive drones. Israeli and U.S. officials said that 99 percent of the incoming munitions were intercepted, suggesting just a few may have struck their intended targets. On Monday, Israel’s war cabinet met for a second day to weigh a response to Iran’s missile and drone attack over the weekend, as the Biden administration says the United States will not take part in any reprisal attacks. World leaders condemned Iran’s barrage and called for restraint.
