WASHINGTON (AP) — Two federal officers fired shots during the encounter that killed ICU nurse Alex Pretti over the weekend in Minneapolis, a Customs and Border Protection official told Congress in a notice sent Tuesday, while Ecuador’s minister of foreign affairs filed an objection saying immigration agents tried to enter the country’s consulate in the city without permission.

Officers tried to take Pretti into custody and he resisted, leading to a struggle, according to a notification to Congress obtained by The Associated Press. During the struggle, a Border Patrol agent yelled, “He’s got a gun!” multiple times, the official said.

A Border Patrol officer and a CBP officer each fired Glock pistols, the notice said.

Investigators from CBP’s Office of Professional Responsibility conducted the analysis based on a review of body-worn camera footage and agency documentation, the notice said. The law requires the agency to inform relevant congressional committees about deaths in CBP custody within 72 hours.

Separately, a man was arrested after he sprayed an unknown liquid at U.S. Rep. Ilhan Omar while she was speaking at a town hall meeting in Minneapolis. The Democrat had just called for the abolishment of Immigration and Customs Enforcement and for Homeland Security Secretary Kristi Noem to resign when she was sprayed.

The developments came a day after President Donald Trump ordered border czar Tom Homan to take over his administration’s immigration crackdown in Minnesota in the wake of Pretti’s death, which was the second fatal shooting this month of a person at the hands of immigration law enforcement.

By sending Homan to Minnesota, “we’re going to de-escalate a little bit,” Trump said during an interview on Fox News’ “Will Cain Show.” That’s significant since White House press secretary Karoline Leavitt, when questioned repeatedly Monday about Homan’s being dispatched to Minnesota, refused to say that doing so was an effort to calm the situation.

The president added of Homan, “Tom, as tough as he is, gets along” with governors and mayors, even in Democratic areas.

As he left the White House on Tuesday, the president was asked whether Pretti’s killing was justified. He responded by saying that a “big investigation” was underway. In the hours after Pretti’s death, some administration officials sought to blame the shooting on the 37-year-old intensive care nurse.

Stephen Miller, Trump’s deputy chief of staff who had initially called Pretti “an assassin,” issued a statement suggesting CBP officers in Minneapolis “may not have been following” protocol. He said the Homeland Security Department’s initial statements about what transpired on Saturday was “based on reports from CBP on the ground.”
