Who Was the Musk Rat Who Barred Members of Congress from Entering a Federal Building? He should be identified and investigated for obstructing Congress

This is outrageous. Who is this guy and on what authority can he prevent sitting members of Congress from access the federal headquarters of the Department of Education? This man needs to be identified and investigated for obstructing Congress.
Here’s a video of the incident:
