A total of 420 votes were cast on the historic debt-limit bill in Washington, but one vote stood out from the pack.

That was, of course, the vote cast by Arizona Democrat Gabrielle Giffords. Her triumphant return to the House of Representatives on Monday was met with a roar of applause, hugs, and high fives from both Republicans and Democrats alike.

Giffords was shot in the head in a Tucson parking lot on January 8 while meeting with constituents. Six people were killed and 13 others, including Giffords, were wounded. The man charged in the shooting, Jared Lee Loughner, was sent to a federal prison facility in Springfield, Mo., after a federal judge concluded he was mentally incompetent to stand trial on 49 charges.

Giffords' surprise entrance just minutes before Monday's vote added even more drama to the high stakes day. She cast her vote for the bill, which passed 269-161.

Here's a look at Giffords' return to congress and her long road to recovery:
