This is reported by the NBC News channel with reference to the draft document.
The charge consists of one article - "incitement to mutiny."
"Donald Trump has committed a serious crime and misdemeanor by knowingly inciting violence against US authorities," the text says.
As a result, it is noted that "the crowd illegally entered the Capitol, injured law enforcement officials, threatened members of Congress and the vice president, and obstructed the most important constitutional obligation to validate the election results."
The authors of the document emphasize that "with all this, President Trump has put the security of the United States and its authorities at serious risk."
Formerly-elected US President Joe Biden accused Trump of knowingly encouraging unrest in Washington.
