What the DOJ may do in the aftermath of the Jan. 6 committee hearings

Joy Reid leads this episode of The ReidOut with a recap of the January 6th hearings, which began with chilling personal stories from the people caught in the middle of the insurrection. Then we learned in great detail how Donald Trump himself caused all of it. On Thursday, we'll watch the season finale, when we'll get the inside story on the 187 minutes Trump spent reveling in the violence he caused while doing nothing to stop it. Joy Reid and her panel discuss this, plus what the DOJ may do in the aftermath of the Jan. 6 committee's findings. Plus, Michael Regan, administrator of the Environmental Protection Agency, joins us on the Biden administration's energy policy in midst of our climate crisis. Finally, the mayor of Highland Park, Illinois, where a gunman opened fire at a Fourth of July parade, testified before Congress on Wednesday to call for a ban on assault weapons. Highland Park Mayor Nancy Rotering joins The ReidOut on the need for a federal approach to ending mass shootings. All this and more in this edition of The ReidOut on MSNBC.
