Police and National Guard troops stood sentry at newly fortified statehouses Sunday ahead of demonstrations planned for the leadup to President-elect Joe Biden’s inauguration, as authorities worked to deter a repeat of the recent riot that overran the U.S. Capitol. A few protesters were starting to gather in some cities, but streets in many others remained empty. In Colorado, a handful of protesters had gathered at the the state Capitol in Denver a little after noon, outnumbered by members of the media. About two dozen people, several carrying long guns, protested outside the Ohio Statehouse, observed by several of the dozens of state troopers positioned around the building.
