WASHINGTON (AP) — President Donald Trump wants Immigration and Customs Enforcement officers to keep pulling over vehicles, signaling his opposition Wednesday to plans announced just a day earlier to suspend most traffic stops following another string of fatal shootings.

It's not clear whether ICE will quickly reverse course and resume most stops, which have been a key tool in Trump's immigration crackdown.

Ending those stops, Trump wrote, would be “playing right into the criminal’s hands.”

“We CANNOT give up one of ICE’s most important and effective Crime Fighting tools, THE TRAFFIC STOP!” Trump wrote Wednesday on his social media site.

Hours after Trump made his views known, Homeland Security Secretary Markwayne Mullin issued his own statement saying people illegally in the country would be “arrested and deported wherever they are.” But Mullin didn't directly say whether ICE officers will be allowed to carry out traffic stops.

ICE's enforcement tactics are coming under renewed criticism after three people died during encounters with federal officers within a week. In Florida, a 28-year-old man was killed Tuesday after he was hit by a tractor trailer while running from immigration and other federal officers, authorities said.

Before that, two motorists were shot and killed by ICE officers — one in Texas last week and another in Maine on Monday.

After the Maine killing, Trump administration officials told ICE officers to suspend most vehicle stops, people familiar with the decision said Tuesday.

Since the immigration crackdown began, federal officers confronting drivers have opened fire several times, saying the drivers’ vehicles had posed a danger. Policing experts have long said that shooting into moving cars presents a danger of its own and should almost always be avoided.

There have been at least 10 deaths involving encounters with immigration agents since Trump launched his deportation campaign. At least four of them involved people in vehicles, a trend so troubling that Republican U.S. Sen. Susan Collins of Maine urged Department of Homeland Security leaders “to cease all non-urgent vehicle stops.”

Two shootings in a week, she said Wednesday, “raise very serious questions” and warrant a halt in that approach for the time being.

ICE has been under pressure to beef up arrest and deportation numbers. It says people being sought are increasingly staying in their homes, and it often blames immigration advocates who advise immigrants to stay in homes unless ICE produces a warrant signed by an independent judge.

ICE officers say that means they’re forced to find other ways to make arrests.

DHS says the man killed in Maine came to the US illegally

More protests are planned for Wednesday, a day after hundreds gathered to remember Johan Sebastián Durán Guerrero, the 25-year-old Colombian national who was shot in his car Monday.

Durán Guerrero illegally entered the U.S. on Sept. 1, 2023, through the southern border, DHS said Wednesday. Advocacy groups said that when he was killed, he was authorized to work in the U.S.

Sen. Angus King, I-Maine, said the Homeland Security secretary told him on Monday that ICE officers were in Biddeford to serve an arrest warrant but that it wasn't for the person who was shot.

When ICE tried to stop a vehicle driven by someone who came from a home under surveillance, the “vehicle attempted to flee the scene and, fearing for public safety, an officer discharged his weapon,” the department said.

It its statement Wednesday, DHS said Guerrero was released into the U.S. after crossing the border.

The department didn't answer questions about the agent who shot him.

Photos showed bullet holes in Durán Guerrero’s car windshield, but the officers involved in the shooting didn’t have body cameras, leaving many questions about what happened.

Maine shooting puts a spotlight on ICE

Outgoing Colombian President Gustavo Petro called the shooting of Durán Guerrero a targeted killing “at the hands of the U.S. government.”

In Wednesday’s social media post, Trump told ICE to be “judicious, fair and smart, and go back and do your very important job.”

Border czar Tom Homan told reporters that the investigation needs to play out and that officers will be held accountable if they are found to have acted inappropriately or illegally.

Maine’s Democratic governor, Janet Mills, said ICE should be scrapped as a federal agency if it can’t be fixed.

Mills, who has criticized ICE before, said Wednesday that the agency needs changes “before more families are robbed of a loved one.”
