A rehearsal for U.S. President-elect Joe Biden's inauguration scheduled for Sunday has been postponed because of security concerns, Politico reported late on Thursday, citing two people with knowledge of the decision.

The rehearsal is now planned for Monday, according to the report.

After last week's riots in Washington, D.C., security officials have locked down the Capitol complex and the U.S. National Guard is expected to deploy more than 20,000 troops to assist with security.
