President Joe Biden is set to deliver his annual State of the Union speech this evening. Several special guests have been invited to attend, among them, Brett Cross, whose son was one of 19 schoolchildren killed by a gunman at Robb Elementary in Uvalde, Texas, last May, and the parents of Tyre Nichols, whose killing at the hands of Memphis police last month prompted murder charges against five officers. Biden will use his address to push for a ban on assault weapons and the passing of the George Floyd Justice in Policing Act.
