The Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) is looking to transfer approximately 20 agents to Chicago in an effort to "beef up" the federal presence in the Chicago city, as two federal law enforcement officials told to CNN on Friday.

Additional agents will form a new task force, which the ATF referred to in the internal documents as the "Chicago Crime Guns Strike Force," in an effort to stem the Chicago's gun violence.

One official said, the increase has been in the works for some time and is not in response to the President Donald Trump tweeting last week.

Earlier, on Friday, the second official could not say for sure that Trump's comment had nothing to do with the decision, by considering its timing. But an ATF spokesperson later said that Trump's administration has not spoken to the ATF about "possible strategies at this time."

There are currently more than 40 agents assigned to the Chicago area, so this transfer would increase that force to more than 60 agents.

The officials told the CNN that ATF headquarters in Washington sent out a bulletin to the field offices around the country on Wednesday looking for agents to volunteer for permanent transfer to the Chicago area.

One official said it is unusual to ask for permanent relocation in reaction to a specific problem. Typically, it would just be an increase of agents for 30 to 60 days.

The bulletin notes that there have been 4,386 shootings and more than 750 homicides in 2016 alone, which is a 58% increase over 2015.

Trump's tweet did not specify anything about what was meant by "feds," but some had questioned whether he intended to send in the National Guards. In the Last week, Emanuel said that the guard would not be welcome but he would appreciate federal help.
