President Trump along with members of the GOP have called for the whistleblower to be identified. Speculation points to the whistleblower being anti-Trump CIA analyst Eric Ciaramella.
Republicans intend to subpoena the whistleblower at the center of the impeachment effort against President Trump.
Rep. Jim Jordan said that Republicans will attempt to get the whistleblower to testify before Congress in a public hearing.
It is unlikely that the whistleblower will testify as Democrats control the House and have veto power over subpoena requests for witness testimony.
Several House Republicans have called on the whistleblower to testify as part of the investigations into Trump's relationship with Ukraine and his July 25 phone call with Ukrainian President Volodymyr Zelensky. The whistleblower complaint alleges that Trump may have improperly pressured Ukraine to investigate political rival Joe Biden and his son Hunter's ties to a Ukrainian energy company.
