Austin and Kenosha shootings, Chauvin trial, NASA: 5 things to know Monday

Shootings in Texas and Wisconsin leave several dead

Mass shootings in Austin, Texas and Kenosha County, Wisconsin, this weekend left several people dead. In Texas' capital city, authorities continue to search for a former sheriff's deputy suspected of fatally shooting three people. Police are pursuing Stephen Nicholas Broderick, 41, and consider him armed and dangerous. Officers said the shooting appeared to stem from a domestic situation and preliminary information indicated that Broderick knew the victims. Meanwhile, in Wisconsin, authorities arrested a "person of interest" in connection with the shooting that left three people dead and at least two more injured at a Kenosha County tavern. The Kenosha County Sheriff's Department said the person in custody will be criminally charged with one count of first-degree intentional homicide with additional criminal charges to follow pending further investigation.

Derek Chauvin trial: Jurors hear closing arguments in murder case

Attorneys for the prosecution and defense in the murder trial of former Minneapolis police officer Derek Chauvin, charged in George Floyd's death, are expected to present their closing arguments Monday. The judge told the jury that they should return to court at 9 a.m. CDT on Monday. What happens next? The judge will instruct the jurors on the laws in the case before the panel members start verdict deliberations. Every trial is different, so accurately predicting the length of jury deliberations is difficult. But legal experts told USA TODAY that Minnesota juries typically have returned verdicts within a few days.

NASA's Mars Ingenuity helicopter makes first powered flight on another planet

NASA made history Monday when the Mars Ingenuity helicopter successfully flew, becoming the first powered, controlled flight on another planet. After an initial failure on April 9, NASA on Friday rescheduled the first flight to 3:30 a.m. ET on Monday after a second high-speed test of the helicopter's rotors proved successful. The triumph was hailed as a Wright Brothers moment. The mini 4-pound copter, in fact, carried a bit of wing fabric from the 1903 Wright Flyer, which made similar history at Kitty Hawk, North Carolina. “We can now say that human beings have flown a rotorcraft on another planet,” project manager MiMi Aung announced to her team. It took three hours for data from the flight to reach Earth: Scientists sweated it out until they got the results in a livestream beginning at 6:15 a.m. EDT.

Supreme Court to weigh key immigration case

The Supreme Court on Monday will hear an appeal in a 2015 case that could impact the status of hundreds of thousands of immigrants in the U.S. living in a state of limbo. At issue in the dispute is whether those who received Temporary Protected Status (TPS) are eligible to apply for green cards even if they initially entered the country illegally. Some 400,000 people, most of them from El Salvador, live in the U.S. under the TPS program, which permits foreign nationals to remain if the administration decides conditions in their country prevent them from safely returning. If the justices uphold the decision, TPS recipients would have to leave the country before applying for lawful permanent residency – with no guarantee of being accepted.

All adults in US eligible for COVID-19 vaccine, per Biden deadline

Monday marks President Joe Biden's deadline for all U.S. adults to become eligible to receive a coronavirus vaccinetwo weeks sooner than his original goal of May 1. However, the White House has made clear that it doesn't mean all Americans will get the vaccine April 19. “It means they can join the line," said White House press secretary Jen Psaki. Using federal guidance on priority populations and projections on vaccine shipments, states have been making their own decisions about when residents can get vaccinated. Psaki said the faster timeline is possible because of the increased vaccine supply and distribution points. On Sunday, Dr. Anthony Fauci said the pause on using the one-shot Johnson & Johnson vaccine will probably be lifted by Friday, although some restrictions may be required.
