This is unusual, to say the least.
>>>Three Minnesota federal prosecutors resigned over the Justice Department’s push to investigate the widow of a woman killed by an ICE agent and its reluctance to investigate the shooter, according to people with knowledge of their decision.
Joseph H. Thompson, who was second in command at the U.S. attorney’s office and oversaw a
sprawling fraud investigation that has roiled Minnesota’s political landscape, was among those who quit Tuesday, according to three people with knowledge of the decision.<<<
Some caution concerning the reason they quit is probably warranted. The source is "people with knowledge of their decision" and the article states "Mr. Thompson, Mr. Jacobs and Ms. Williams declined to discuss the reasons they resigned."
Trump might eventually run out of people who are willing to participate in questionable investigations and court filings.
