Congresswoman Gabrielle Giffords announced via Twitter, Facebook, and YouTube Sunday that she will resign from Congress so she could focus on recovering from the assassination attempt that almost took her life.
"I have more work to do on my recovery, so to do what is best for Arizona I will step down this week," Rep. Giffords tweeted to her 76,750 Twitter followers.
The tweet included a link to the Democrat's website which included a video on YouTube titled "A Message from Gabby" where she got into more detail explanation behind her resignation.
Nearly a year ago in a parking lot in Tucson, Arizona, a gunman killed six people and injured 15, including Giffords who was holding a small town hall meeting.
"I don't remember much from that horrible day, but I will never forget the trust you placed in me to be your voice. Thank you for your prayers and for giving me time to recover," Giffords stated in her two-minute video.
In wake of the resignation, former Speaker Nancy Pelosi released a statement saying that Giffords "has been a true bright star."
"Gabby's message of bipartisanship and civility is one that all in Washington and the nation should honor and emulate," Pelosi wrote.
President Barack Obama was effusive in his praise for the congresswoman, saying Giffords "embodies the very best of what public service should be."
According to a press release from her office, Giffords intends to submit her letter of resignation later this week to Arizona Gov. Jan Brewer and House Speaker John Boehner. Special elections will be held to determine her replacement.
