FILE - In this Jan. 6, 2021 file photo, Colorado State Patrol troopers hold on to a patrol vehicle as they keep watch on people attending a rally in support of President Donald Trump outside the State Capitol in downtown Denver.  Statehouses where Trump loyalists have rallied since the Nov. 3 election are heightening security after the storming of the U.S. Capitol this week. Police agencies in a number of states are monitoring threats of violence as legislatures return to session and as the nation prepares for the inauguration of President-elect Joe Biden.
