“I wouldn’t put myself hopefully in that kind of position, but if I was in a position like that, that’s what I would do,” Ensign said. “He’s going to have to answer that for himself.”

“It is unfortunate the senator chose to air this very personal matter, especially after the Hamptons did everything possible to keep this matter private,” the lawyer said. “It is equally unfortunate that he did so without concern for the effect such an announcement would have on the Hampton family. In time the Hamptons will be ready and willing to tell their side of the story.”

A former campaign aide to Sen. John Ensign confirmed her involvement Wednesday in an extramarital affair with the conservative Republican, lamented his decision to “air this very personal matter” and said she eventually would tell her side of the story.

An attorney for Cindy Hampton and her husband, Doug, issued a statement on their behalf as Ensign phoned in his resignation as a member of the Senate GOP leadership. The senator’s aides refused to return phone calls seeking additional details about a dalliance that pushed the 51-year-old Nevada lawmaker’s political career to the brink of disaster.

An Associated Press review of federal records showed Cynthia Hampton received a promotion and a pay raise around the time of the affair at one political entity controlled by Ensign and a pay raise at a second. Her husband was an employee in Ensign’s Senate office.

The disclosure resurrected questions about a two-week period in 2002, when Ensign abruptly dropped from public view. A person familiar with that episode, speaking on condition of anonymity because of the sensitivity of the matter, said Tuesday the senator told a close associate the absence followed an earlier affair.

Her salary also doubled at Ensign’s campaign committee, where she was treasurer, beginning around the time the affair began. It went from $500 a month to $1,000 a month.

Records also show Doug Hampton received a monthly salary of $13,555 as an administrative assistant in Ensign’s Senate office. He received a payment of $19,679 for his final month of employment and was off the payroll on May 1, 2008, according to Senate records.

Additionally, the National Republican Senatorial Committee made twice-monthly payments, generally $500 apiece, to Brandon Hampton, who Republican officials said was the couple’s son. The payments began in March of last year and ended in August, when Ensign’s office says the affair ended.
