The DHS is expected to send about 150 Homeland Security agents to Chicago to help local law enforcement deal with a spike in crime, according to an official.
The agents, who are generally used to investigate human trafficking, drugs and weapons smuggling, are expected to stay in the city for at least two months, according to the source.
It is not clear how they will back up local law enforcement or when they will arrive, but they will make arrests for federal crimes, not local ones.
A spokesman for Homeland Security said the department does not comment on “allegedly leaked operations”.
In a tweet on Sunday, the president blamed local leaders for violence in Chicago and other cities.
“The Radical Left Democrats, who totally control Biden, will destroy our Country as we know it. Unimaginably bad things would happen to America,” Trump tweeted, referring to his likely Democratic opponent, Joe Biden.
“Look at Portland, where the pols are just fine with 50 days of anarchy. We sent in help. Look at New York, Chicago, Philadelphia. NO!”
It is his latest effort to use an agency — created after the September 11 attacks to protect the country from terrorists threats — to supplement local law enforcement in ways that have alarmed critics.
Demonstrators who have been on the streets for weeks have found renewed focus in clashes with camouflaged, unidentified agents outside the city’s US courthouse.
Protesters crowded in front of the courthouse and the Justice Centre late on Monday night, before authorities cleared them out as the loud sound and light of stun grenades filled the sky.
Homeland Security agents have also been deployed to the Mexico border along with national guard troops during the crisis there.
But with the border largely closed because of coronavirus and the number of illegal crossings plummeting, the president has turned the department on to what he sees as a threat within the US and one that similarly plays to his base: violence following police reform protests that have rocked the nation since the death of George Floyd.
In Chicago, the president of the local police officer’s union wrote Mr Trump a letter asking “for help from the federal government” to help combat gun violence.

The city has seen 414 homicides this year, compared with 275 during the same period last year, and a spate of shootings in recent weeks as cities around the country have seen an increase in violence.
