Armed federal immigration officers in tactical gear moved through terminals at some of the busiest U.S. airports Monday, standing near security lines and checkpoints after President Donald Trump ordered their deployment during a partial government shutdown that has disrupted air travel nationwide. The officers have not screened passengers so far. The Trump administration said they would supplement Transportation Security Administration staffing at certain airports but provided few details about exactly what they would be doing. After intensified immigration enforcement and protests in cities across the country over the past year, their presence has unsettled some travelers and raised new questions.

Gregory Bovino says he plans to retire from the U.S. Border Patrol in the coming weeks. He became a face of the Trump administration’s aggressive immigration enforcement tactics in large cities. Bovino joined the Border Patrol in 1996 and steadily rose through the ranks but wasn’t well-known outside the agency until last June, when he took command of a crackdown in Los Angeles. Bovino was a near-daily presence as Minnesota’s Twin Cities turned into a battleground between demonstrators and immigration authorities in January that led to the deaths of U.S. citizens Renee Good and Alex Pretti.

A Minnesota county attorney may pursue charges against federal officers for alleged misconduct during an immigration crackdown in the Minneapolis area. The prosecutor says Monday her office is already investigating 17 incidents in the county, including a Jan. 21 case where Border Patrol official Greg Bovino threw a smoke canister at protesters, and a Jan. 7 arrest near a high school where officers used chemical irritants while students and staff were in the area. Her office may also sue the federal government for blocking requests for evidence in her investigations into the deaths of Renee Good and Alex Pretti. The Department of Homeland Security responded saying that states cannot prosecute federal officers.

Surveillance video of a nearly blind refugee from Myanmar being dropped off at a Buffalo doughnut shop by Border Patrol agents five nights before he was found dead shows him pacing by a locked door and walking through an empty parking lot. The video obtained by the Investigative Post shows Nurul Amin Shah Alam stepping gingerly in his county-issued jail booties and pulling up his hood against the cold. It was recorded on Feb. 19, the day the 56-year-old was released from the county jail where he had been held for a year. Buffalo Mayor Sean Ryan has said the restaurant was closed at that time. U.S. Customs and Border Protection said this week that agents chose “a warm, safe location” for the drop off.

President Donald Trump says he wants the U.S. to take ownership of the Gaza Strip and redevelop it after Palestinians are resettled elsewhere. He made the remarks in a joint press conference with Israeli Prime Minister Benjamin Netanyahu. Earlier Tuesday, Trump’s Middle East envoy said that a three to five-year timeline for the reconstruction of Gaza is not a viable post-war plan for the battle-torn territory. This first visit of a foreign leader during Trump’s second term comes amid lagging support for Netanyahu in Israel.
