WASHINGTON, Jan. 13 (Xinhua) -- U.S. President Donald Trump on Wednesday called on the Americans not to engage in violence next week, in which the inauguration ceremony will be held for President-elect Joe Biden.

"In light of reports of more demonstrations, I urge that there must be NO violence, NO lawbreaking and NO vandalism of any kind. That is not what I stand for, and it is not what America stands for. I call on ALL Americans to help ease tensions and calm tempers. Thank You," the president said in a statement released by the Office of the White House Press Secretary.

On Monday, Trump approved an emergency declaration for Washington, D.C., effective through Jan. 24, covering the date of Biden's inauguration, which falls on Jan. 20.

The Federal Bureau of Investigation has warned about plans of armed protests from Jan. 16 through Jan. 20 at all the 50 state capitols, and from Jan. 17 through Jan. 20 at the U.S. Capitol in Washington.
