On Thursday, the Defense Department said that in order to blend in, special-operation forces often don the insignia of forces they accompany. On Friday, after Turkey complained, a spokesman called the action “unauthorized and inappropriate.”
On Sunday, President Barack Obama and Vice President Joe Biden were officially sworn in for a second term. Obama will deliver his inaugural address on Monday, with the ceremony expected to begin around 11:30 a.m.
The military is playing a big role in Monday's events. An escort of 2,300 military personnel -- including each service’s honor guard -- will accompany the two-to-three hour inaugural parade in the afternoon. Almost two dozen federal, state and local agencies are involved in security for the day, according to a list from Mark Knoller of CBS. They range from the Federal Aviation Administration to the Justice Department to the U.S. Park Police.
