The investigation into the deadly January 6th insurrection is picking up some steam. The House Jan. 6 Committee already issued four rounds of subpoenas with the most recent one summoning Jeffrey Clark, a Trump administration Justice Department official. A former U.S. Capitol Police whistleblower also came out with a letter accusing two of the department's top officials of failing to share vital intelligence report in the days ahead of the riot and lying to Congress. Darrin Porcher, criminal justice professor at Pace University and a former NYPD lieutenant, joined Cheddar Politics to discuss more on the latest development.
