The four major broadcast outlets — CBS, NBC, ABC and Fox — combined for a 16.3 overnight rating during the address Tuesday night, which could result in total viewership of approximately 49 million when final numbers, to include the cable news networks and other outlets, are in later Wednesday.

ADVERTISEMENT That would make Trump's speech the biggest one based on TV ratings out of any of the major speeches he has delivered since taking office.

The rating for Trump's Tuesday night address is better than his first State of the Union Address in January 2018, which delivered a 14.8 overnight rating, or 45.6 million viewers, across the same networks in 56 metered markets.

The 16.3 rating is also higher than Trump's first address in office, which wasn't officially a State of the Union but a speech to a joint session of Congress. That address, in January 2017, registered a 16.0 rating, or 48 million viewers.
