U.S. Sen. Chuck Grassley suggested on Friday that the FBI might leak reports of its investigation into presidential candidate Hillary Clinton’s use of a private email server as secretary of state.

Grassley, Iowa’s senior senator and chairman of the Senate Judiciary Committee, said an anonymous and unauthorized release of FBI investigative materials could result if officials at the agency believed prosecution of Clinton was stymied for political reasons.

“Is there going to be political interference? If there’s enough evidence to prosecute, will there be political interference?” Grassley wondered aloud during a breakfast meeting with the Des Moines A.M. Rotary club on Friday. “And if there’s political interference, then I assume that somebody in the FBI is going to leak these reports and it’s either going to have an effect politically or it’s going to lead to prosecution if there’s enough evidence.”

The senior senator’s musing came in response to a long answer to a very general question from one of the Rotarians about the status on inquiries into the email server and Clinton’s handling of the 2012 terrorist attack on a diplomatic post in Benghazi, Libya.

Both issues for years have plagued Clinton, the leading Democratic presidential candidate.

When asked by Radio Iowa reporter O. Kay Henderson after the breakfast if he was suggesting the FBI should leak investigative findings, Grassley expounded on his comment.

“I wouldn’t be encouraging it because if it’s a violation of law, I can’t be encouraging a violation of law,” he said. “This is kind of my own opinion, this is something I’ve heard.”

Several congressional panels — including Grassley’s Judiciary Committee — have looked into various aspects of the email controversy. The FBI has been investigating the matter for months as well, and reportedly has several dozen agents working on it.

A former Clinton staffer is cooperating with that investigation, and it’s believed Clinton herself will be questioned.
