Hillary Clinton burst into uncontrollable laughter Friday when asked by CNN host Jake Tapper about the ongoing controversy surrounding her use of a private email server as secretary of state.

Tapper brought up a comment Clinton's 2016 rival Bernie Sanders made during this week's debate in which he said he was tired of hearing about her "damn emails."

"There are a lot of people who are not," Tapper said as Clinton burst out into laughter.

Tapper continued, with Clinton still laughing, "Including FBI officials looking into whether national security was compromised."

The likely Democratic nominee's reaction was immediately panned by the Republican National Committee.

“State Department rules, a federal judge, and the Obama Administration’s own guidelines have all made clear what she did was not allowed,” spokesman Michael Short said in a statement. “While Hillary Clinton may think she can mislead and laugh off tough questions about her judgment, her growing email scandal personifies why an overwhelming majority of Americans don’t trust her.”

Others chimed in on Twitter.

New strategy for Hillary: Maniacally laugh whenever anyone brings up your emails and ongoing FBI investigation. https://t.co/RQm0Q8olrk
