Cohen is /ourguy/
He fucked the DNC on every question.
No way they would ask those questions if they knew the answers
Did he say everything the DEMs wanted, or did he debunk everything that was important.
The only damage if you even want to call it that would be the old claim of muh racist and muh porn stars.
Other than that Cohen debunked everything important about the Russia Hoax
Lawyer 101 - don't ask questions you don't already know the answer to.
Cohen and Schiff agreed on answers, and Cohen fucked them.
Otherwise he would not have been asked.
