The memo was dated Jan. 28 and signed by by Acting Director Todd Lyons.
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.
The FBI agent who began investigating the officer-involved shooting of Renee Good has resigned from the bureau, sources tell ABC News.
After the agent attempted to begin a civil rights investigation, she was told to reclassify it, according to a source.
The New York Times first reported this detail.

Federal agents were seen deploying tear gas at protesters who assembled near the location of a reported shooting involving a federal agent.
There were no immediate reports of arrests.
Gov. Tim Walz said in a statement that there was a shooting Saturday in Minneapolis that involved a federal agent.
Walz said he spoke with the president about the situation.
"Minnesota has had it. This is sickening," he said. "The President must end this operation. Pull the thousands of violent, untrained officers out of Minnesota. Now."
The city of Minneapolis said in an X post Saturday they are looking into reports of a shooting involving federal officers near 26th Street W and Nicollet Ave.
A worker at a nearby business confirmed to ABC News that they witnessed a shooting and said they were “currently dealing with the fallout.”

Hundreds of Minneapolis businesses closed Friday in support of a protest against ICE operations in the city, and streets around the downtown area were filled with protesters, according to ABC Minneapolis station KSTP.
Despite subzero temperatures, large crowds of people carrying signs and demanding "ICE out" marched through the streets.
The protest remained peaceful and there were no reports of arrest or unrest.
