Security lines Pennsylvania Avenue in Washington, Monday, Jan. 21, 2013, prior to the start of the 57th Presidential Inaugural Parade which will take place following President Barack Obama's ceremonial swearing-in on Capitol Hill. WASHINGTON (AP) - Inauguration-goers are complaining about a slow-moving security gate at the National Mall. Authorities say the orange gate, located between Union Station and the U.S. Capitol, was stalled so a motorcade could pass and barriers could be repositioned. Stuck spectators vented on Twitter that the line did not move for at least a half-hour and that there were repeated chants of "Orange gate." Some said they were redirected to the blue security gate, a block away.
