Prosecutors disclosed in a Lower Manhattan courtroom Wednesday Michael Cohen has provided “credible” and “valuable information” at the heart of the Russia inquiry.

But prosecutor Jeannie Rhee, a top aide to special counsel Robert Mueller, said not all of Cohen’s information concerning Russia has been revealed.

Cohen spokesperson Lanny Davis said Trump’s former fixer would be willing to appear before Congress – testifying in front of any committee charged with investigating Russian election meddling.
