OK— found it: “Effective February 9, 2017, Dana Boente became Acting Deputy Attorney General upon the confirmation and swearing in of Jeff Sessions as Attorney General and will serve in that position until DAG Nominee Rod Rosenstein is confirmed.”
This was because Sally Yates was canned after she refused to uphold Trumps immigration order-— so technically, there was a succession from Yates to Channing Phillips (the obama re-selection) that was changed by Trump to Boente... until Rosenstein is confirmed.
Thank you for bringing that up. TRUMP did act fast when it was discovered that Bark had finagled a dope of his a PERMANENT deputy, in the event of an AG not being able to serve.
Trump reversed it, pronto. Thx.
