I forget, was he President or Senator at the time?
Trump on one occasion said to Howard Stern something along the lines of “Yeah, I guess maybe we had to do it...”
Otherwise Trump articulated an argument against the war, which was a very unpopular position at the time.
The idea that Lauer should have “proven” Trump a liar is ridiculous leftist bias.
The tactic is to always take one thing Trump says out of a long appearance and run around shouting that he lied or did something disqualifying. And then there is reality.
