State Department Inspector General Steve Linick is giving an “urgent” briefing to congressional staffers Wednesday afternoon about documents from the Office of the Legal Adviser related to Ukraine and State.

According to ABC News, the meeting will occur in a secure location on Capitol Hill.

Since Congress is still in recess, the urgency of the meeting suggests a link to the reporting surfaced recently about the State Department’s role in coordinating interactions between Rudy Giuliani and Ukrainian officials. Secretary of State Mike Pompeo also admitted Wednesday morning for the first time that he was part of the July 25 call with President Donald Trump and Ukrainian President Volodymyr Zelensky.

The State Department has been a central player in the rapidly unfolding Ukrainian scandal, with Pompeo trying to hold back the breaking dam by insisting that he will not allow department officials to testify before a slew of House committees.
