Philadelphia Inquirer reporter Jonathan Tamari posted the following on Twitter yesterday afternoon:

Judicial news: @SenBobCasey has returned blue slip on 3d District nominee Stephanos Bibas, clearing way for hearings. 1 of few Ds to do so

He meant Third Circuit. He added:

BUT, Casey has also told Trump admin he’d use blue slip to block atty David Porter if he’s nominated.

The overview of the Third Circuit nominations picture that I posted last month is here.

UPDATE: Orin Kerr just posted the news on Volokh Conspiracy, here.

UPDATE2: The first tweet is wrong about Casey being one of “few” Democratic senators to return a blue slip on a Trump circuit nominee. I’m informed by Glenn Sugameli of Judging the Environment and Lena Zwarensteyn of American Constitution Society that Casey is the 7th to do so, against only 3 who’ve withheld blue slips.
