The Uvalde school district fired a newly hired school officer after CNN identified her as a former Texas state trooper who is being investigated for her response to the mass shooting at Robb Elementary that left 19 children and two teachers murdered. Crimson Elizondo is one of the law enforcement officers who arrived at the school within two minutes of the gunman entering the building and opening fire. It took police officers around 77 minutes to kill the shooter while children and teachers were dying or already dead. CNN Crime and Justice Correspondent Shimon Prokupecz has been covering the mass shooting and investigations into the police’s response. He tells Anderson Cooper the reason the school district is claiming Elizondo was fired.  Plus, Georgia Republican Senate candidate Herschel Walker has doubled down on his denials that he allegedly paid for a woman’s abortion in 2009. Van Jones is a CNN Political Commentator and was a special adviser to the President during the Obama administration. He joins AC360 to discuss Walker's denials and his response to the allegations.
