Also in Washington more signs the Mueller investigation may be wrapping up as newly unsealed search warrants for Michael Cohen, hundreds of documents released at the request of ABC news and other news organizations revealed how long trump's fixer was on Mueller's radar.

In another clue that the special counsel's office is focusing all efforts on their final report, we're learning Mueller's team has requested more time to respond to a court request to unseal records in Paul manafort's case.
