Who is Pat Cipollone? Former Trump White House Counsel testified before Jan. 6 committee

President Donald Trump's former White House Counsel Pat Cipollone was called to testify last week before the House select committee investigating the Jan. 6 attack on the Capitol. Cipollone was subpoenaed to testify last month, after former White House aide Cassidy Hutchinson mentioned him multiple times during her testimony. Who is Pat Cipollone? 

Several witnesses have testified that Cipollone was one of the main White House officials who opposed attempts by Mr. Trump and his allies to overturn the results of the 2020 election. The Select Committee investigating the insurrection says there is evidence that Cipollone repeatedly raised legal and other concerns about Mr. Trump's activities on Jan. 6 and the days leading up to it.
