District security officials and federal agencies are preparing for possible protests around Tuesday’s State of the Union address and likely arrivals of trucker convoys later this week, though it remains unclear what might actually materialize and how serious it could be.

Still, local and federal officials said Monday that few things are being left to chance.

A fence has been reinstalled around the U.S. Capitol; the usual road closures will be in effect around the Capitol on Tuesday; hundreds of National Guardsmen will be deployed to help with traffic management; police officers from Philadelphia, Baltimore, and New York will be on hand to assist local and federal police departments; and trucks and buses have been staged around the city to help block access to certain streets if necessary.

Speaking at a press conference on Monday, officials said they will both respect people’s right to peacefully protest while also ensuring that any illegal or disruptive activity is handled quickly.

“We regularly handle peaceful demonstrations and welcome all to the nation’s capital to exercise their First Amendment rights,” said D.C. Police Chief Robert Contee. “I should also note that citizens of our great city have a right to enjoy peace and tranquility within community and unobstructed freedom of movement.”

“While there is a possibility that some may come to our city with the intent of going beyond what is allowed as a constitutional right and seek to engage in unlawful acts or acts of civil disobedience, it is my hope that guests to our city will abide by the laws of the District of Columbia. I want to be very clear that we are prepared to take swift law enforcement actions for violations of our local and federal laws, if necessary,” he added.

Pamela Smith, the chief of the U.S. Park Police, said that a permit for a protest for 1,000 to 3,000 people who support the trucker convoys has been approved for Tuesday at the Sylvan Theater by the Washington Monument.

“We are committed to the peaceful assembly and First Amendment expression of the First Amendment activities, but we will not tolerate any illegal activities,” she said.

While he would not specify how many trucks D.C. may allow to enter the city, should that come to pass, Contee added that police would be ready to respond to any trucks that seek to block local streets. That would start with seeking voluntary compliance, but then possibly arresting people who refuse to comply. Contee urged residents to prepare for possible disruptions and plan for other ways to get around.

“One of the great things about our city is there are oftentimes other modes of transportation. If it becomes necessary, please consider those options,” he said.

Chris Rodriguez, the director of the city’s Homeland Security and Emergency Management Agency, added that local and federal officials would be working together to prepare for any possible Russian disinformation campaigns around any of the trucker convoy protests.

“Certainly there is the potential for Russian disinformation. This wouldn’t be the first time the Russians have done that across the United States in the last several years. So we are working with our national and regional partners to make sure we’re distilling what is real and what is not and sharing that information,” he said.

As for how long the more obvious security preparations would stay in place, Bowser said that the National Guard deployment was planned through March 7, while a representative of the U.S. Capitol Police said that a decision would be made shortly after the State of the Union on when to remove the fencing.

“Sometimes you don’t know what you don’t know, and we want to be in a posture of preparedness,” said Contee, responding to an overall question about the extent of the security preparations that will be on hand this week. “While we expect for the best, we prepare for the worst.”
