YES! It was The State Department!!
"On Monday, an update to the U.S. State Department site said President Trump’s time in office was ending on Jan. 11, before the page was removed.
“Donald J. Trump’s term ended on 2021-01-11 19:49:00,” what appeared to be a sparse bio page for Trump on the State Department website said Monday afternoon. A bio for VP Mike Pence also had the same message. Users on social media noticed the changes just before 3 p.m. ET; within an hour, both pages were rendered inaccessible."
