Congressional aides say the special House committee investigating the 2012 attacks on the U.S. mission in Benghazi, Libya, will issue subpoenas for former Secretary of State Hillary Rodham Clinton's personal emails.

The aides say that possible as early as Wednesday, the committee will seek the additional material from the potential 2016 Democratic presidential candidate.

The aides spoke on condition of anonymity because they were not authorized to publicly discuss the committee's actions.

The Associated Press reported on Wednesday that a computer server that sent and received Clinton's emails — on a private account she used exclusively for official business while secretary of state — traced back to an Internet service registered to her New York home.

The Washington Post first reported about the subpoenas.
