Ok so I learned how Berman got to be the US Attorney for the southern district of New York. Sessions originally appointed him to a 120 day temporary appointment to serve until Trump could appoint a permanent replacement. I haven’t seen but suspect that Schumer et al didn’t give their blessing — surprise —and so under a statute the judges in the district appointed him to the position. I’m pretty sure they were a bunch of leftist judges given that they were approved for New York. The important thing to understand is that he was never nominated by Trump and approved by the senate.
