Former Secretary of State Hillary Clinton joked about the ongoing investigation over her use of a private email server while at the State Department, telling a group of Iowa Democrats that the hubbub is just “politics.”

Speaking to about 2,000 Democrats at the Iowa Democratic Wing Ding at the historic Surf Ballroom in Clear Lake, Iowa, Clinton was defiant about the controversy and her use of the personal account, days after turning over her private server to the Justice Department. The agency is probing the handling of classified information on the server—with the U.S. intelligence community saying the account contained at least two emails that should have been labeled Sop Secret.

“You may have seen that I recently launched a Snapchat account,” Clinton said at the start of her 25-minute address. “I love it. I love it. Those messages disappear all by themselves.”

Later, reflecting on Republican attacks on her over the terrorist attack in Benghazi in 2012, Clinton referenced the ongoing investigation.

“You know what, it’s not about emails or servers either—it’s about politics,” Clinton said, her voice rising as the crowd of Democratic loyalists cheered. “I will do my part to provide transparency to Americans, that’s why I’m insisting 55,000 pages of my emails be published as soon as possible. I didn’t offer to answer questions for months before Congress. I just provided my server to the Justice Department. But here’s what I won’t do. I won’t get down in the mud with them. I won’t play politics with national security or dishonor the memory of those who we lost.”

“I won’t pretend that this is anything other than what it is: the same old partisans games we’ve seen so many times before,” Clinton added. “So I don’t care how many super PACs and Republicans pile on. I’ve been fighting for families and underdogs my entire life and I’m not going to start now.”
