Lessons the Jan. 6 panel could take from the 9/11 Commission

The House select committee's investigation into the Jan. 6 insurrection is one of the highest-profile investigations of its kind since the commission on the 9/11 attacks nearly 20 years ago. That bipartisan group worked for almost two years, holding public hearings before releasing its findings. It was chaired by former New Jersey Gov. Thomas Kean, who joins Judy Woodruff to discuss.
