The decision to erect the fencing again, comes as officials in Washington prepare for trucker convoys that are planning protests against pandemic restrictions beginning this week. The Pentagon has already approved the deployment of 700 unarmed National Guard troops to be used to assist with traffic control during potential demonstrations. The D.C. National Guard also activated 400 Guard members Saturday to help.

This is related to several truck convoys expected to hit the D.C. region next week. The convoys originated in California, and are driving across the country to D.C.

Some groups plan to rally the same day as President Biden's first State of the Union Address. Other groups may also arrive in the area on Wednesday. The groups, which are modeling their protest after similar ones in Canada, are demanding an end to coronavirus mandates across the country.

There have no official participant numbers released, but reports say thousands of people are taking part in the protest.

Manger said Capitol Police have also requested additional assistance from outside law enforcement agencies before Tuesday’s address.

Metropolitan Police Department Chief Robert Contee has said his department is closely monitoring the shifting information and would be devoting additional policing in a rolling state of heightened alert over the next few weeks.
