President Donald Trump said on Wednesday his administration was removing the National Guard from Chicago, Los Angeles and Portland but he added in his social media post that federal forces will "come back" if crime rates go up, Reuters reported. 

Local leaders in those cities and Democrats have said the deployments, which have faced legal setbacks and challenges, were unnecessary. They have accused the Trump administration of federal overreach and of exaggerating isolated episodes of violence to justify sending in troops.

Trump, a Republican, has said troop deployments in Los Angeles, Chicago, Washington, D.C., Memphis and Portland were necessary to fight crime and protect federal property and personnel from protesters, according to Reuters.
