He was only “acting” for a few months, see my #283
I see your point.
Wiki shows this:
“On April 25, 2018, the judges of the Southern District of New York, pursuant to 28 U.S.C. § 546(d), unanimously appointed Berman U.S. Attorney for an indeterminate term that expires “until the vacancy is filled”[3] which may or may not include the appointment of a Presidential nominee being approved by the Senate.[4][3]”
This strikes me as a “permanent temporary” job.
