Hillary Clinton today defended her use of a personal email address while at the State Department as a matter of “convenience.”

The former secretary of state, and likely 2016 Democratic presidential candidate, addressed the controversy in New York, following an event on women's empowerment at the United Nations headquarters.

She also briefly addressed her use of a private email server, but said it contains personal communications between her and her husband.

"The server will remain private," Clinton said.

Tonight on “The Kelly File,” Sen. Rand Paul (R-Ky.), Judge Andrew Napolitano, Brit Hume, and Joe Trippi react to Clinton’s question-and-answer session with the media.

During her news conference, Clinton also joined the White House and Democrats in slamming Sen. Tom Cotton (R-Ark.) and other Republican leaders for their letter to Iran. Tonight, Cotton joins Megyn Kelly to discuss the controversial letter.

Don’t miss “The Kelly File” tonight at 9p/12a ET on Fox News Channel.
