President Donald Trump took unprecedented steps toward federalizing Washington, D.C. on Monday, saying it’s needed to fight crime even as city leaders pointed to data showing violence is down.He took command of the police department and deployed the National Guard under laws and Constitutional powers that give the federal government more sway over the nation’s capital than other cities.

The president's decision to federal the D.C. police force and deploy the National Guard could garner legal challenges depending on how it is carried out.
