Former National Security Adviser Michael Flynn just said he will not comply with a subpoena issued by the Senate.
Although the Senate subpoena carries no legal bearing, the Senate could get the Department of Justice involved with the investigation.
Per the Daily Caller:
Congress is looking for information regarding six phone calls Flynn made with Russian Ambassador Sergei Kislyak:
Former National Security Adviser Michael Flynn will not honor a Senate Intelligence Committee subpoena requesting any documents detailing his interactions with Russian officials during the 2016 campaign, the Associated Press reports.
Refusing the subpoena could be the first step in a larger legal process for the former National Security Adviser:
Flynn previously refused to turn over the documents to Senate Intelligence Committee prompting the subpoena in the first place.
Flynn could be held in contempt of Congress, but would likely challenge the action in federal court. The legal proceedings could drag on for years, Austin Wright explained in a Politico essay Monday. He continued that Senate leaders would have decide if he was in contempt of court if he refused to comply and that the investigation would then head to the Department of Justice. The department would have to then decide whether to file charges, or a federal district court would civilly enforce the order.
