when did tours of the white house stop
White House Visitors Office Tours were suspended in the wake of the September 11, 2001 attacks due to terrorism concerns. In September 2003 they were resumed on a limited basis for groups making prior arrangements through their congressional representatives and submitting to background checks. They were again suspended in March 2013 during the Obama administration, due to the effects of the ongoing budget sequestration, but were resumed again in November 2013.[20]
