Rep. Cooper: We may have to arrest Postmaster General

04:34

Congressman Jim Cooper (D-TN) joins Hallie Jackson as members of Congress look to subpoena Postmaster General Louis DeJoy in order to compel him to testify before them. Cooper says these steps aren't taken lightly, and is willing to wield the full force of the law, including holding DeJoy in contempt and possibly arresting him if does not agree to appear before the committee.
