Why would Trump have kept Micheal Cohen around for over 10 years if he didn't bring something of value to Trump.com?

He comes across as a retarded, half conscious bag man, but he doesn't seem evil? Cohen has a history with Trump business going back to 2008.

He is acting?

He cant be that dumb to purger himself live, with the best lawyers Democrat's can buy, on TV, LIVE, for EVERYONE to see????

Great shows need great actors. Cohen is either the lovable but really bad cousin we all try to help grow their organic potato business, or a over 10 year planted spy into Trump organization.
