May order military to stop anti-police protest: US President Donald Trump

U.S. President Donald Trump said on Saturday that states and cities must get "much tougher" on anti-police protests or the federal government will step in, including by using the military and making arrests.

"Liberal Governors and Mayors must get MUCH tougher or the Federal Government will step in and do what has to be done, and that includes using the unlimited power of our Military and many arrests," he said in a tweet.
