Alex Pretti was confronted on a Minneapolis street by an officer who was later on the scene of his shooting, video analyzed by CNN shows.

Alex Pretti -- the ICU nurse who was fatally shot by a Border Patrol agent in Minneapolis, Minnesota -- gave a final salute to a veteran he treated at a VA hospital ... according to new video shared by the deceased veteran's son.

Alex Pretti, shot by a Border Patrol agent, was an ICU nurse. Kristi Noem suggested that he was a domestic terrorist. Others say he was "genuine," "good."

People who knew a man fatally shot by federal agents pushed back against what they called a smear campaign by federal officials. “He was a good man,” his family said.

Bill Clinton has today condemned the killing of Alex Pretti by federal agents as “unacceptable” and warns the Trump administration’s dishonesty about the “horrible scenes” coming out of Minneapolis is a direct and possibly fatal threat to American democracy.

The decision to place HSI in the lead investigative role is unusual and has raised questions among current and former federal law enforcement officials.

Federal officials have claimed Alex Pretti, who was fatally shot by at least one Border Patrol agent in Minneapolis Saturday, “brandished” a firearm to officers.

Over $530,000 had been donated by the afternoon of Jan. 25, a little over a day after Pretti, an ICU nurse, was shot and killed by a Border Patrol agent.
