WASHINGTON (AP) — Paul Manafort's former son-in-law says he has been so busy with special counsel Robert Mueller's investigation that he's been unable to keep up with his other legal issues.

That's according to a court filing and a lawyer involved in a civil lawsuit against him.

The confirmation of Jeffrey Yohai's extensive involvement with Mueller's ongoing investigation comes as he has been caught up in another investigation in New York and has reportedly cut a plea deal with federal prosecutors in California.

The developments could increase the pressure on Manafort, President Donald Trump's former campaign chairman, who suffered a setback in his legal defense earlier this week when a judge denied his motion to dismiss charges filed against him.
