A group of protesters upset over Donald Trump’s election were captured on video blocking two Air Force officers from crossing a makeshift “checkpoint” they established on the streets of Washington, D.C. on Friday.

The infuriating footage comes from Ryan Lovelace of the Washington Examiner.

The video begins with a protester telling an approaching Air Force officer that he and another officer could not pass through to the inauguration entrance because the checkpoint they had established was closed. A woman in the human barricade can also be seen following and pointing at one of the officers, as if to signal her fellow protesters to not let the men through.

Chants of “this checkpoint is closed” can be heard in the background.

The two officers did not argue with the protesters and simply moved along, seemingly to another entrance point.

Having failed to defeat Trump in the November election, protesters are now turning to protest in various forms to denounce the Republican president. In addition to human walls and other forms of civil disobedience, some protesters began destroying property and breaking the windows of businesses and banks on the streets of the Capitol.
