This weekend Hillary Clinton said she was “eager” to be interviewed by the FBI in regards to the agency’s investigation into her use of a private email server while secretary of state. Clinton then declined to say who told her the setup was legal and whether it violated government regulations for the handling of classified material.

Clinton was interviewed Saturday morning at the FBI headquarters in Washington, D.C. and her campaign said the three-and-a-half hour interview was voluntary.

Clinton told MSNBC in a phone interview Saturday evening that the interview was something she had offered to do since last August. She stated “I’ve been eager to do it, and I was pleased to have the opportunity to assist the department in bringing its review to a conclusion.” She also stated that she has no knowledge about when the FBI will conclude its case before sending its recommendation to Attorney General Loretta Lynch.

Clinton also defended her use of the private server by repeatedly stating she “never received nor sent any material that was marked classified,” but acknowledged that some of the emails have been “retroactively” re-classified.

When asked who advised her about the server, Clinton said: “I’m not going to go into any more detail then I already have in public many times … out of respect for the process that the department is conducting.”

The server controversy then intensified Thursday when Bill Clinton, had a questionable meeting with Lynch, on the tarmac at a Phoenix airport.

On Saturday Donald Trump called for charges to be filed against Clinton in the case. He Tweeted, “It is impossible for the FBI not to recommend criminal charges against Hillary Clinton. What she did was wrong! What Bill did was stupid!”

Republican National Committee Chairman Reince Priebus said: “Hillary Clinton has just taken the unprecedented step of becoming the first major party presidential candidate to be interviewed by the FBI as part of a criminal investigation surrounding her reckless conduct.”

Priebus also stated the encounter between Bill and Lynch “raises serious concerns about special treatment.”
