Former President Trump's White House counsel Pat Cipollone will testify Friday in a closed-door, videotaped interview with the Jan. 6 committee, a source familiar with his plans told Axios.

Why it matters: Cipollone — a crucial witness to what unfolded inside the West Wing on Jan. 6 — was subpoenaed by the committee following former Trump White House aide Cassidy Hutchinson's blockbuster testimony late last month.

Driving the news: Cipollone's subpoena has been extended to Friday, the source briefed on the deal told Axios, so he is still in compliance with it.
