If I were required by a judge to keep going in my closing argument past 6:30 pm, I would be very glad to have evidence like this to perk up my jury, where the sole substantive defense witness calls his putative client (Cohen) an "asshole" and makes it clear he is in league with Trump.
Since I started as a practicing attorney 30 years ago, I have consistently told my clients: "Never put anything in an email that you would not want to see in 18 inch headlines on the front cover of the New York Post."
