Mike Pence has received his first national security briefing since becoming Donald Trump's running mate.
Pence's briefing Friday lasted about two hours and was held at an Indiana National Guard base in Indianapolis.
The Republican Indiana governor said afterward that he was "grateful" for the "thorough and informative" briefing.
Pence said he couldn't discuss specifics due to classified nature, but vowed that he and Trump would be "ready on day one" should they be elected in November.
He did not take questions afterward, but said he was honored to take part in the tradition, which he says extends back to the time of Harry Truman.
