Lawmakers today are questioning law enforcement officials reactions to the riot.
Here's a Live link to the hearing
The hearing Today before a pair of senate committees will include testimony from three officials who resigned after rioters disrupted the joint sessions of Congress, imperiling lawmakers and Vice-President Mike Pence, who was presiding over the vote count that cemented Joe Biden's win over Trump.
The joint hearing before the Rules Committee and the Homeland and Governmental Affairs Committee is expected to focus on why officials weren't better prepared for the attack and why it took so long to repel the mob from a building that had been considered one of the most secure in the world.
The hearing is just the beginning in understanding what happened on January 6th as there will be other hearings (federal and civil) in the near future.
