House Judiciary Committee chairman and impeachment champion Jerry Nadler is apparently a bit of a diva.

Nadler, who is reportedly away from Washington to tend to a family emergency, was spotted today on a DC-bound Amtrak train by Brad Blakeman, a former George W. Bush aide and regular Fox News guest.

“Look who is on my Amtrak Acela train from NYC to DC!” Blakeman wrote on Facebook earlier today with two photos of Nadler standing in the aisle.

“I witnessed first hand Nadler’s snippy sense of entitlement when I caught up with him in the Cafe Car. He demanded that the attendant take the cheese off his hamburger before serving him. When she hesitated he had a hissy fit.

“She told him: ‘calm down sir.’ That only got him more pissed. At that point I left with my order. What an A-hole,” Blakeman wrote.

Nadler had been in New York tending to a “family emergency.” Politico reported:

House Judiciary Chairman Jerry Nadler is tending to an undisclosed family emergency in New York City and will miss the last procedural step before articles of impeachment come to the floor, a committee aide confirmed Tuesday.

Nadler is expected to return to Washington late Tuesday or early Wednesday before the impeachment vote.
