As per this article, Lauer is not Jewish:

His father was Jewish, but as you know in Judaism the religion of a child is determined by that of the mother. Since Matt's mother wasn't Jewish, neither is he. And I've never heard him say a word or give any other indication that he embraced the religion of his father.
And of course, some of the biggest anti-Zionists are Jewish, from Noam Chomsky to Bobby Fischer.
Matt's sister, April, was a roomie of a friend of mine during college. She was brought up Jewish, as, I would assume Matt was. And the college is VERY close to where you sit (wink, wink).
Bobby Fischer is a Seventh-Day Adventist, I believe.
