Kentucky Republican Sen. Rand Paul named the alleged whistleblower Eric Ciaramella and called for him to testify as part of the impeachment hearings.

During a Wednesday interview on Washington, D.C.-based WMAL, Paul was asked about a controversial remark he made last week when he called for the press to name the whistleblower but refused to do so himself. On Wednesday, Paul named Ciaramella and said he should be brought in to clarify whether he is indeed the whistleblower.
