Pat Cipollone appears before federal grand jury investigating Jan. 6
Why it matters: Cipollone, with his deputy Pat Philbin, who is also expected to appear before the grand jury, are among the two highest-profile witnesses to testify in the Department of Justice's criminal investigation into the riot, Reuters notes.
The big picture: Both Cipollone and Philbin have been subpoenaed by the grand jury investigating the riot.
- Cipollone, a crucial witness into President Trump's final days in office, previously spoke to the House Jan. 6 select committee in a closed-door interview.
- Former White House aide Cassidy Hutchinson testified that Cipollone had warned in the days before the attack that Trump and his aides could be charged with "every crime imaginable" if he joined protesters at the Capitol.
