The House Committee on Foreign Affairs will hold a hearing next week on the conflict in Libya, the committee announced Wednesday.

The hearing, titled “Libya: Defining U.S. National Security Interests,” is scheduled for 10 a.m. Wednesday in the Rayburn House Office Building. Secretary of State Hillary Clinton is thus far the only witness invited to testify.

The announcement comes on the fifth day of U.S. and allied intervention in Libya and as members of Congress express increasing concern about the U.S. role in the conflict there.

Indiana Sen. Richard G. Lugar, the top Republican on the Senate foreign relations committee and one of the earliest skeptics in Congress of U.S. involvement in Libya, wrote committee Chairman John F. Kerry (D-Mass.) on Wednesday to request that their panel hold such a hearing as well.

And earlier Wednesday, House Speaker John Boehner (R-Ohio) sent a lengthy letter to President Obama that included a list of unanswered questions about the U.S. involvement in the conflict.

The House committee hearing on Libya will mark the first time that the foreign affairs panel will use its online “You Ask a Question” feature, through which members of the public may submit questions that may be asked by committee members at the hearing.
