Representative Darrell Issa (R-Calif.), the top ranking Republican on the Oversight and Government Reform Committee, says he will file an ethics complaint against Representative Joe Sestak (D-Pa.) if he doesn’t provide details about an alleged illegal job offer from the White House.
Sestak, who recently defeated Senator Arlen Specter (D-Pa.) in the Democratic primary, said in February that the Obama administration offered him a high-ranking cabinet position if he dropped out of the race.
During an interview May 23 on NBC’s Meet the Press, Sestak reiterated his claim, but refused to provide specifics regarding the allegation.
"I was offered the job," he said. "Anything that goes beyond that is for others to talk about."
Meanwhile, White House Press Secretary Robert Gibbs said during a separate interview on Meet the Press that the administration’s lawyers had looked into the claim, and found that "nothing inappropriate" happened.
"It is unacceptable for an administration that touts itself as the ‘most transparent’ in history to continue to stonewall a significant and potentially devastating accusation of political corruption," responded Republican National Committee Chairman Michael Steele.
Issa said that he will file a formal complaint with the House Ethics Committee if an investigation into Sestak’s allegation is not launched, Politico.com reports.
"Either he’s lying, or covering up felonies for political purposes," said Issa.
