A top House Republican may file an ethics complaint against Rep. Joe Sestak if he refuses to give more information about the Obama administration’s alleged effort to get him to quit Pennsylvania’s Democratic Senate primary in exchange for a job.

Rep. Darrell Issa of California, the ranking member of the House Committee on Oversight and Government Reform, said his panel is obligated to investigate the claims because they involve three felonies, including offering a bribe and interfering with an election.

“If Congressman Sestak will not tell us, then to be honest the only choice we have is to deal with this from a standpoint of congressional integrity,” Issa told The Washington Examiner. “Under our ethics rules, either Congressman Sestak is lying, which would be an ethical violation, or he is covering up three felonies by members of the administration, which of course would be an ethical violation.”
