Another thing that's different about this year's presidential address to Congress — no "designated survivor."
Usually, for a president's address to Congress, a top official camps out at a secure location in case of an attack and the president and all cabinet officials are killed.
But since a lot of top officials will be watching virtually this year, the White House says there's no need for a designated survivor.
Treasury Secretary Janet Yellen would reportedly be the next in line of succession in the event of a disaster.
