Washington (CNN) Republican Rep. Duncan Hunter pleaded guilty on Tuesday to federal corruption charges stemming from his misuse of more than $200,000 in campaign funds.

Hunter, who represents the northeastern San Diego area, had previously denied dipping into campaign funds to pay for a slew of personal expenses, including video games, an Italian vacation, groceries and bedding.

Hunter pleaded guilty to one count of conspiracy to misuse campaign funds and now awaits sentencing. Though he faces up to five years in prison, Assistant US Attorney Phillip Halpern told CNN following the guilty plea that he would seek a sentence of about 14 months. He also said he has not ruled out jail time for Hunter's wife, Margaret, who pleaded guilty to a similar charge earlier this year.

The prosecutor hinted at the possibility that Hunter, who was first elected in 2008, will resign from office, though he told reporters that it "was not part of negotiations."

"It is understood from the defense team that he will in fact resign," Halpern said. "Rather than reelection, Mr. Hunter now faces resignation, disgrace and imprisonment."
