President Trump said Friday that he's sending "federal help" to Chicago to deal with the city's spate of gun violence.

He posted the news in a tweet.

Crime and killings in Chicago have reached such epidemic proportions that I am sending in Federal help. 1714 shootings in Chicago this year! — Donald J. Trump (@realDonaldTrump) June 30, 2017

Agents from the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) are expected to hold a joint news conference Friday afternoon with officials from Illinois State Police and the Justice Department to "announce a major partnership to target gun violence in Chicago", according to the chief communications officer for Chicago police.

The Chicago Sun-Times reports that 20 ATF agents have been sent to Chicago to combat gun violence and are working with the city's police department and state police on a "strike force." Chicago's police department personally asked Attorney General Jeff Sessions for additional resources a few months ago.
