Washington D.C. -- At the presidential inauguration today, attendees viewing from the overflow area cheered wildly at the sight of President Obama and Sen. John Kerry (D-Mass.), but weren't as thrilled when they spotted a few others.

The event was packed, from the Capitol down the National Mall to the Lincoln Memorial. Overflow areas several hundred yards from the Capitol, were also filled with attendees, most of which were Obama supporters.

More than once, people barred off from the main seating areas attempted to jump over and under the blockades to get closer to the spot Obama would take the oath of office. The high amount of security, however, prevented any rowdiness that may have occurred.

"There's Jill Biden!" one attendee remarked, looking at the live feed of the event projected on the jumbo screen put up in front of the Capitol building. After a moment of getting a better look at the woman on the screen and seeing that it was actually Callista Gingrich, wife of former Republican presidential candidate Newt Gingrich, the attendee and a few others laughed then booed loudly.

When Rep. Paul Ryan (R-Wis.) was shown the screen entering the inauguration area, he too was booed by some attendees. "They should have booted him out," one woman said.

House Speaker John Boehner (R-Ohio) was also booed when he was shown on screen.
