Pat Sajak, Chris Harrison, others react to Alex Trebek's cancer diagnosis

I’ve said this before but Alex Trebek is in a way the last Cronkite: authoritative, reassuring TV voice you hear every night, almost to the point of ritual.

The Sajak family is deeply saddened to hear of Alex Trebek’s struggle with cancer. Our hearts go out to him and his family. But there is no one I know who is stronger and more determined, and I would never bet against him. We, and the entire country, are pulling for you, Alex.

I just want to say to Alex Trebek I know you can kick cancers ass. You are the true daily double and the ultimate Jeopardy! champion in my eyes.
Lots of positive energy coming your way from so many sir.
