A 37-year-old man was shot and killed Saturday morning in Minneapolis -- the second shooting of a U.S. citizen this month by federal agents in the city.
The shooting of Alex Pretti, an ICU nurse, ratcheted up tensions, as protesters clashed in the streets with law enforcement in the aftermath of the shooting.
The incident followed the fatal shooting of Renee Good, a 37-year-old mother, on Jan. 7.
Secretary of Homeland Security Kristi Noem and Chief Advisor Corey Lewandowski met with Trump for almost two hours on Monday, according to the New York Times.
It was at her request, according to the Times, and her job reportedly isn't in jeopardy.

A federal appeals court on Monday granted the government's request to maintain a stay of a federal judge's order that barred immigration agents from arresting protesters or using non-lethal weapons against them.
Earlier this month, U.S. District Judge Katherine Menendez ruled that federal agents deployed to the state were prohibited from such retaliatory actions. The Eighth Circuit Court of Appeals stayed that order last week, and on Monday, they moved to keep that stay in place.
Following the deadly shooting over the weekend, attorneys for the ACLU filed an emergency motion to lift the appellate court's stay, writing that the incident "created an urgent need for intervention to prevent irreparable injury to the named plaintiffs, protesters, and observers."
The government subsequently filed an emergency motion to maintain the stay. In the decision, which denied the ACLU’s motion while granting the government's, the court stated it reviewed video evidence and found "observers and protestors engaging in a wide range of conduct, some of it peaceful but much of it not.
"They also show federal agents responding in various ways," the court said. "Even the named plaintiffs' claims involve different conduct, by different officers, at different times, in different places, in response to different behavior."

President Donald Trump said that he just had a "very good" phone call with Minneapolis Mayor Jacob Frey.
"Lots of progress is being made!" Trump said in a post on social media.
Frey said he "appreciated" the call with Trump, during which the mayor said he "expressed how much Minneapolis has benefited from our immigrant communities and was clear that my main ask is that Operation Metro Surge needs to end."
"The president agreed that the present situation cannot continue," Frey said in a statement on social media.
"Some federal agents will begin leaving the area tomorrow, and I will continue pushing for the rest involved in this operation to go," he added.
Trump said that border czar Tom Homan will meet with Frey on Tuesday "to continue the discussion."
The call follows Trump's phone call with Minnesota Gov. Tim Walz earlier Monday.
