Republican Mark Sanford, the former South Carolina governor whose extramarital affair derailed his political career, returned to Congress on Wednesday with his Argentine "soul mate" at his side.

"Terrorists murdered four Americans, we demand the truth," reads a terse new petition for White House transparency on the Benghazi attacks, organized by the American Center for Law and Justice and signed by 77,000 people. "President Obama: With continually changing stories and inaccurate accounts, the American people have been misled. Terrorists attacked American soil —; our embassy — we need the truth and accountability," the petition says.

Mark Sanford's plea for forgiveness succeeded with South Carolina voters on Tuesday, and now his Republican colleagues will have to decide whether they, too, can forgive him.

Former South Carolina Gov. Mark Sanford — once a rising star in the Republican Party whose career crashed four years ago after a bizarre extramarital affair — capped a remarkable political comeback Tuesday by winning a special election for the state's open House seat.

Republican Mark Sanford's campaign for South Carolina's open House seat was slumping two weeks ago when he gambled on a stunt many at the time ridiculed: He "debated" a life-size poster-photo of House Minority Leader Nancy Pelosi.

"We will make them pay," South Korea President Park Geun-hye said of the fate of North Korea should it launch an attack of any size or scope on her nation, to CBS News.

With Republican candidate Mark Sanford surging ahead in Tuesday's special congressional election in South Carolina, the party is increasingly hopeful it can avoid an embarrassing defeat in a district that analysts said it should have been able to hold easily.

"Today, the National Rifle Association is a record 5 million strong. Even as thousands of Americans join our cause every day, the media and political elites denigrate us. They cringe at the sight of long lines at gun shows. They mock Americans who are buying firearms and ammunition at a record pace. They scorn and scold the NRA. They don't get it, because they don't get America."

After giving Mark Sanford the cold shoulder for months, the Republican establishment slowly is warming to the former governor's campaign for South Carolina's open House seat, with several key Republicans weighing in with endorsements in recent days.
