Michael Flynn's family has set up a legal defense fund and is now soliciting donations as multiple investigations scrutinize the actions of the former Trump national security adviser.

The family is setting up the fund because "[t]he enormous expense of attorneys' fees and other related expenses far exceed their ability to pay," according to a statement from Joe Flynn and Barbara Redgate, Flynn's brother and sister, respectively.

A source familiar with his legal representation said Flynn's "core team" is seven attorneys from Covington — including partners, counsel, and associates — with "numerous" others involved at certain points. The fees will "certainly be into the seven figures," according to the source.

Flynn, who played key roles in Trump's campaign and is a retired Army lieutenant general, has been under scrutiny in the various investigations relating to Russia's attempts to influence the 2016 election, including special counsel Robert Mueller's investigation. Flynn tweeted out the news about the legal defense fund first thing Monday.
