Due to security concerns, an inauguration rehearsal scheduled for Sunday has been postponed, two people with knowledge of the matter told Politico.
Additionally, President-elect Joe Biden canceled a Monday Amtrak trip from Wilmington, Delaware, to Washington, D.C. In the wake of last week's riot, the Capitol complex is locked down, with a heavy law enforcement presence. There have been threats of violence linked to armed protests planned for all 50 states over the weekend and leading up to the inauguration.
Lisa Monaco, a former Homeland Security adviser and Biden's nominee for deputy attorney general, has been working with the Biden transition team as a temporary adviser on inauguration security. On Wednesday, Biden was briefed by the FBI, Secret Service, and national security officials on the various threats that have been made. In a statement, the Biden transition team said there is "the potential for additional violence in the coming days," and this is "a challenge that the president-elect and his team take incredibly seriously."
