"We may intercede," Trump said. "We may do something to get that whole thing cleaned up."
He pointed to the "liberal establishment" and sanctuary cities run by "very liberal people" to blame for this crisis.
"It's a phenomenon that started two years ago. It's disgraceful," Trump said in response, seeming to refer to when he took office in 2017.
According to data from the Department of Housing and Urban Development, homelessness overall has decreased by 15% since 2007. Between 2016 and 2018, the rate of homelessness has stayed between 550,000 to 553,000 per year, the HUD figures show.
Trump then shifted the conversation to police officers he said are getting are getting "very sick" while walking their beats and office workers headed down sidewalks to their jobs.
"We have to take the people and do something. We have to do something," Trump said. "That's not really the kind of work that the government probably should be doing. We never had this in our lives before in our country."
While Trump said that he has been fighting this problem in Washington, D.C., and is looking into addressing homelessness in other cities, he gave no specifics.
