ATLANTA -- Gov. Mark Sanford arrived in the Hartsville-Jackson International Airport this morning, having wrapped up a seven-day visit to Buenos Aires, Argentina, he said. Sanford said he had not been hiking along the Appalachian Trail, as his staff said in a Tuesday statement to the media.

Sanford's whereabouts had been unknown since Thursday, and the mystery surrounding his absence fueled speculation about where he had been and who's in charge in his absence. His emergence Wednesday ended the mystery.

Sanford, in an exclusive interview with The State Media Company, said he decided at the last minute to go to the South American country to recharge after a difficult legislative session in which he battled with lawmakers over how to spend federal stimulus money.

Sanford said he had considered hiking on the Appalachian Trail, an activity he said he has enjoyed since he was a high school student.

"But I said 'no' I wanted to do something exotic," Sanford said "... It's a great city."

Sanford, in a brief interview in the nation's busiest airport, said he has been to the city twice before, most recently about a year and half ago during a Commerce Department trip.

Sanford said he was alone on the trip. He declined to give any additional details about what he did other than to say he drove along the coastline.

Sanford, who was wearing a blue and white button down shirt and brown denim pants, said he left for Buenos Aires on Thursday night from Columbia International Airport and had originally planned to come back tomorrow.

Media reports said a SLED SUV the governor drove that night was spotted in the airport's parking lot.

The governor said he cut his trip short after his chief of staff, Scott English, told him his trip was gaining a lot of media attention and he needed to come back.

When asked why his staff said he was on the Appalachian Trail, Sanford replied, "I don't know."

Sanford later said "in fairness to his staff," he had told them he might go hiking on the Appalachian Trial.

Sanford said he decided not to return via the Columbia airport to avoid the media. The State Media Company was the only media who greeted Sanford this morning.

"I don't know how this thing got blown out of proportion," Sanford said.

Sanford said he has taken adventure trips for years to unwind. He has visited such places as the coast of Turkey, the Greek Isles and South America. He was with friends sometimes and sometimes by himself.

"I would get out of the bubble I am in." Sanford said.

Sanford said the legislative session was a difficult one for him, particularly losing the fight over whether he should accept stimulus $700 million in stimulus money he wanted lawmakers to spend on debt instead of urgent budget needs.

"It was a long session and I needed a break," Sanford said.

After a brief conversation with a reporter, Sanford was escorted away by an aide.
