I recall that tweet. Dovetails with the report from May 2023 quoting source close to the Pelosi family:
“The political thinking is that if DiFi stays as long as possible, it helps Schiff”
"If DiFi resigns right now, there is an enormous probability that ...Lee gets appointed"
“It’s very tricky, & political...they want [Feinstein] to stay” in Senate as long as possible.
source "spoke on condition of anonymity to speak candidly about a sensitive situation"
