The Daily Caller reports:

South Carolina Rep. Trey Gowdy suggested earlier this week that the public will be surprised when it hears how the FBI described Sidney Blumenthal and his working relationship with his longtime friend, Hillary Clinton.

Gowdy, the former chairman of the House Select Committee on Benghazi, mentioned in passing during an interview with Fox News’ Megyn Kelly that the FBI had quizzed Blumenthal as part of its probe into Clinton’s private email server.

Blumenthal, a former journalist and Bill Clinton White House aide, had dodged when asked in several interviews back in May about whether he was interviewed. He said that he did not want to comment on an ongoing investigation.

Gowdy noted that when Blumenthal’s emails with Clinton were made public last year, Clinton bristled when Blumenthal was described as her adviser. But the FBI thought he was even more than a mere adviser, Gowdy suggested.

“You’ll never guess what term the FBI used when they described Sidney Blumenthal and his relationship to her,” the Republican told Kelly.

A true mystery.
