DES MOINES, Iowa (AP) — Kamala Harris will “exponentially” increase the time she’s spending in Iowa. Bernie Sanders is shaking up his operations there and in New Hampshire. And Beto O’Rourke is going broader, turning up at such places as a San Quentin prison and an Arkansas gun show.

With just over four months until the Iowa caucuses usher in the battle for the Democratic nomination, candidates are shifting their approaches to the state. Some are betting the changes will pay off closer to the caucuses. Others are lowering expectations by looking beyond Iowa.

DALLAS (AP) — The chief of the Federal Aviation Administration tested the Boeing 737 Max in a flight simulator Thursday, but the FAA declined to say how its updated anti-stall software performed.

That software kicked in before two Max jets crashed, and fixing it is central to Boeing’s effort to get the grounded airplane flying again.

New FAA chief Stephen Dickson said his agency has no timetable for reviewing changes that Boeing is making to the plane.

Dickson also toured the Max assembly line near Seattle and met with senior Boeing officials.

WASHINGTON (AP) — The U.S. announced Thursday that it is expelling two Cuban diplomats and restricting travel of members of Cuba’s permanent mission to the United Nations as leaders gather from around the world for the annual U.N. General Assembly.

The Cuban diplomats who are being expelled are attached to the U.N. mission and tried to “conduct influence operations against the United States,” State Department spokeswoman Morgan Ortagus said. She provided no details on the allegations and the diplomats’ names weren’t released.

AURORA, Colo. (AP) — Democratic presidential candidate Beto O’Rourke says he’s open to broadening his proposal to require owners of AK-47s and AR-15s to sell them to the government.

During an emotional town hall Thursday near the site of the Colorado theater shooting, a man who identified himself as a survivor of the 1999 Columbine massacre noted that the shooters there didn’t use the military-style weapons O’Rourke wants to take. They instead used regular semi-automatic weapons. He challenged O’Rourke to confiscate those arms as well.

CHINA, Texas (AP) — The slow-churning remnants of Tropical Storm Imelda flooded parts of Texas on Thursday, leaving at least two people dead and rescue crews with boats scrambling to reach stranded drivers and families trapped in their homes during a relentless downpour that drew comparisons to Hurricane Harvey two years ago.

Officials in Harris County, which includes Houston, said there had been a combination of at least 1,000 high-water rescues and evacuations to get people to shelter. The storm also flooded parts of southwestern Louisiana.
