"Everyday that the Senate fails to send assault weapons ban to the President’s desk, or waits to take another actions is a day too late for families and communities impacted by gun violence," White House spokesperson Karine Jean-Pierre told reporters on Monday.
St. Louis Police Lt. Col. Michel Sack said on Monday that three individuals have been killed in the incident, including the gunman.
Jean-Pierre called the incident an act of "senseless violence" and urged taking additional actions to stop gun violence in the United States.
