"Which will be very important because they've already received subpoenas to appear in Adam Schiff's basement on Thursday", he joked, referring to the House of Representatives intelligence committee chairman who has led the inquiry into whether Trump should be impeached for pressing Ukraine to investigate a political rival of his.

Nadler requested that Trump RSVP by 6 p.m. December 1.
