Trump reveals plan to patrol Washington streets with police and military forces

"I'm going to be going out tonight with the police and with the military, of course," Trump said in an interview Thursday with radio host Todd Starnes. 

"We are seeing really substantial effects because these guys are busting their a--," Vance said Wednesday. 

"Right here in Union Station, you have vagrants, you have drug addicts, you have the chronically homeless, you have the mentally ill who harass, who threatened violence, who attacked families," Vance said. "And they've done it for far too long. This should be a monument to American greatness." 

Under the 1973 Home Rule Act, a temporary federal takeover of the Metropolitan Police Department is authorized for emergency situations up to 30 days. After that time-frame expires though, Congress must step in and approve any extensions. However, similar restrictions don't exist for D.C. National Guard troops in the Home Rule Act. 

Vance also signaled Wednesday extensions could occur, depending on how much progress is made over the next few weeks. 

Meanwhile, Washington officials filed a lawsuit challenging the Trump administration's move to federalize local police Friday.

"By illegally declaring a takeover of MPD, the Administration is abusing its temporary, limited authority under the law," Washington, D.C., Attorney General Brian Schwalb wrote in a Friday X post. "This is the gravest threat to Home Rule DC has ever faced, and we are fighting to stop it."Fox News' Patrick Ward contributed to this report.
