Sen. Dianne Feinstein (D-CA) came under fire during now-SCOTUS Justice Amy Coney Barrett’s confirmation process for not being aggressive enough, with some Democrats even calling for her to step down from her post due to her age.

According to a new report from the New Yorker’s Jane Mayer, Feinstein — at the age of 87 — has been “seriously struggling” with her cognitive health for some time, affirming rumors that have been running rampant in D.C. 

Mayer wrote on Thursday that insiders familiar with Feinstein’s health confirmed the rumors that the California lawmaker is suffering from cognitive decline.

According to Mayer, sources revealed that Feinstein’s short-term memory “has grown so poor that she often forgets she has been briefed on a topic, accusing her staff of failing to do so just after they have.”

Feinstein’s handling of Barrett’s confirmation process sparked such outrage that she even announced last month that she would be stepping down as ranking member of the Senate Judiciary Committee.

Mayer claimed that the situation has gotten so dire that Senate Minority Leader Chuck Schumer (D-NY) has been forced to have “serious and painful talks” with Feinstein over her reported signs of mental decline.

“Schumer had several serious and painful talks with Feinstein, according to well-informed sources. Overtures were also made to enlist the help of Feinstein’s husband, Richard Blum,” Mayer claimed. “Feinstein, meanwhile, was surprised and upset by Schumer’s message.”

One Capitol Hill aide working for a different Senator told Mayer that Feintstin is “an incredibly effective human being, but there’s definitely been deterioration in the last year. She’s in a very different mode now.”
