ABC News – Rep. Gabrielle Giffords has made no decision about whether she’ll run for re-election to Congress, rumors and news reports to the contrary, her spokesman said this morning.

“The congresswoman is focused on her recovery,” the spokesman said. “Nothing has changed.”

Giffords, D-Ariz., returned to Congress Monday night for the first time since being shot in the head in January, casting a vote in support of the compromise debt-ceiling bill.

“Gabrielle has returned to Washington to support a bipartisan bill to prevent economic crisis,” read a message posted to Giffords’ Twitter account while members began casting their votes on the House floor.

Minutes later, Giffords, 41, slowly entered the chamber to loud, sustained applause and a standing ovation by her colleagues, who huddled around her to give hugs, kisses and handshakes.

“You know we’ve had in this fight the most grizzled, hardened hearts harden even further and they all melted when she walked in the chamber,” Rep. Debbie Wasserman Schultz, D-Fla., told ABC’s Robin Roberts. “I’ve never heard, we have a lot of applause for various reasons in the House chamber, never like this. It was thunderous.”

Vice President Joe Biden, with a big smile on his face, walked to the House floor and said, “I came to see Gabby, that’s why I’m here.”

In the hallway just outside, Giffords’ husband, astronaut Mark Kelly, was all smiles as well.

“It feels good,” he said as his wife was casting her first vote since the tragedy. “Great actually.”

Democratic Minority Leader Nancy Pelosi of California said of Giffords as she was leaving the House floor Monday, “It was above and beyond the call of duty. She’s a heroine … an inspiration.”

Pelosi said she had known Giffords was coming to the Hill for this vote for some time, but didn’t want to say anything until it happened. The two spent some time on the floor talking Monday evening.

“We had our girl talk. Had girls’ hugs and all of that. So it was pretty thrilling, personally and officially,” Pelosi said. “She honored us with her presence.”

Congresswoman Schultz said she was most impressed by the Giffords’ progress.

“It’s one thing for her to see and recognize friends of hers and close colleagues; she walked up into the Capitol and when she saw Bill Livingood, our sergeant-at-arms, she said, ‘Livingood,’ and gave him a big hug. It was just amazing, it really was.”

Biden said he and Giffords “commiserated about the steps of recovery.”

“She’s remarkable,” Biden said. “Will matters. She is the embodiment of a strong, strong, strong woman. Think about what she’s been through. And think about her determination.”
