Sen. Tom Coburn’s (R-Okla.) office said Monday that he has not been subpoenaed by the Senate Ethics Committee over his involvement in a scandal involving Sen. John Ensign (R-Nev.) and his affair with a former campaign aide.

Several news outlets have reported in recent days that the Ethics panel had begun issuing subpoenas for former Ensign aides. The subpoenas come in the face of fresh charges by Doug Hampton, the husband of Ensign’s former mistress, Cynthia Hampton.

Coburn lived with Ensign at the time of the affair and counseled his Nevada colleague on the situation. Although Coburn has acknowledged discussing the relationship with Ensign and talking to Doug Hampton, he has denied any wrongdoing, saying he has primarily acted as Ensign’s spiritual adviser.

But despite his high-profile role, Coburn has not been subpoenaed, according to his spokesman John Hart, who said, “We have not— been contacted by the Ethics Committee.

It is unclear whether the Ethics Committee has subpoenaed Ensign. When asked if the committee has served him, Ensign spokeswoman Rebecca Fisher said simply that, “Sen. Ensign is confident he followed all ethics rules and laws, and he will cooperate with any official inquiries.—
