Trump tweeted Friday morning that "Crime and killings in Chicago have reached such epidemic proportions that I am sending in Federal help".
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 pace of murders in Chicago is on track with figures from a year ago, which was the city's deadliest in two decades.
Shortly after his inauguration, Trump tweeted "If Chicago doesn't fix the disgusting "carnage" going on, 228 shootings in 2017 with 42 killings (up 24% from 2016), I will send in the Feds!".
According to the Sun-Times, there were about 760 killings in 2016, the deadliest year in Chicago in the past two decades. The new agents will join the roughly 35 to 40 ATF agents who are already there as part of an initiative formulated in November, when former President Barack Obama was still in office.
It felt like old times on Friday morning as President Donald Trump tweeted about Chicago violence, although there was at least some tangible action to accompany this one.

Chicago Police Superintendent Eddie Johnson said in a statement that law enforcement is "foundationally changing the way we fight crime in Chicago", according to the AP. The 2016 homicide rate of 27.7 murders per 100,000 was the city's highest since the mid-1990s.
The team will include an additional 20 ATF agents, who arrived in early June, according to a city official, as well as Chicago police officers, IL state troopers, intelligence analysts and state and federal prosecutors.
"The Trump Administration will not let the bloodshed go on; we can not accept these levels of violence", Sessions said in a statement on Friday afternoon.
Chicago is among a number of so-called sanctuary cities, which provide some protection to illegal immigrants under laws that limit cooperation between local police and federal immigration authorities.
Collins said in an email that the mayor's office has for months said it would welcome additional federal support and that city police have made progress even "without any of the new resources from the federal government we requested". And he noted that dozens of additional ATF agents had "surged" into Chicago so far this year.
