See video at link, starting at about 1:24:30. It is then about a 3 minute video until the end. After President Trump left the House floor last night, Nancy Pelosi banged her gavel stating both Houses were "dissolved." Shortly thereafter, she banged the gavel again calling the House to order, and then left the House floor. A man (not sure who, sorry) then took the podium and recognized Steny Hoyer who called for the SOTU speech to be entered into the record, and called to adjourn the session.
