WASHINGTON (ABC News) – The State Department’s inspector general is expected to brief staffers from several House and Senate committees on Wednesday afternoon about documents obtained from the department’s Office of the Legal Adviser concerning documents related to the State Department and Ukraine, sources familiar with the planned briefing told ABC News.

Details of the briefing, expected to be conducted by Steve Linick, the inspector general at State, remain unknown. Linick is expected to meet with congressional staff in a secure location on Capitol Hill.

The unusual nature and timing of the briefing – during a congressional recess – suggest it may be connected to a recent intelligence community whistleblower allegation which describes, in part, the State Department’s role in coordinating interactions between Rudy Giuliani, the president’s personal attorney, and Ukrainian officials.

The State Department has faced criticism in recent weeks for connecting Giuliani to multiple Ukrainian officials about re-opening an investigation into for Vice President Joe Biden and his son, Hunter.

The State Department’s press office and the State Department’s inspector general’s office did not immediately respond to a request for comment. The committees expected to be part of the briefing did not immediately respond as well.

This is a developing news story and will be updated once information becomes available.
