Michael Flynn will invoke his Fifth Amendment right against self-incrimination in refusing to comply with a Senate subpoena seeking records relating to the intelligence committee's investigation into the Trump campaign's Russia connections, a source close to Flynn tells BuzzFeed News.

The subpoena called for a response by Wednesday, but the source told BuzzFeed News that Flynn — President Trump's former national security adviser — will be responding on Monday.

Given the many calls to investigate and prosecute Flynn, the source said, it would be "highly imprudent for him to comply with the subpoena." Flynn will invoke his Fifth Amendment right against self-incrimination not to do so, the source added.

The Associated Press reported earlier Monday that "a person with direct knowledge of the matter" expected Flynn to take such steps on Monday.

As BuzzFeed News previously reported, Flynn's decision doesn't mean he will be going to jail for contempt of Congress. The process for such a prosecution is complex and rarely attempted — let alone successful.
