Aside from Steve Bannon, three other Trump allies also face subpoena deadlines this week.
Two of them, Trump's former chief of staff Mark Meadows and former administration official Kash Patel, have been "engaging" with the committee, according to the panel, though it remains unclear if that contact amounts to any form of cooperation.
The select committee agreed to short postponements of Patel's and Meadows' appearances as they continue to engage with the investigation, a committee aide told CNN on Thursday.
But while Patel and Meadows appear to have bought themselves more time, the committee made clear Thursday its patience is limited. Rep. Adam Schiff echoed that sentiment in an interview Thursday, providing a rare window into how the committee is approaching talks with these individuals.
Schiff described Patel to MSNBC as "demonstration of the principle in the Trump administration that the more willing you were to do anything the President wanted, no matter how unscrupulous, the higher and faster you could rise."
"And he rose Phoenix-like through the Trump administration one position after another, even being contemplated to take over the CIA," Schiff said, adding that Patel was "an evil Zelig."
The committee was able only recently to serve Trump's former deputy chief of staff Dan Scavino a subpoena, a source familiar with the matter told CNN, and his deadline to appear for a deposition has likely been delayed.
Bannon was scheduled for a deposition in front of the committee on Thursday, and Bannon's lawyer wrote in a letter the day before to the panel saying that his client will not provide testimony or documents until the committee reaches an agreement with former President Trump over executive privilege or a court weighs in on the matter.
