Chaiman and CEO of General Electric Jeffrey Immelt:

Everyone at GE and at NBC Universal is devastated by the loss of our colleague and friend Tim Russert. Tim was a giant in journalism and a face and a voice that America trusted. He earned that trust through hard work, love of his profession and, above all, through his enduring honesty and integrity. And most importantly, Tim was a wonderful human being who valued family and friends over all. We will miss him greatly. My sincerest sympathies go out to Tim's family and to the many people whose lives he touched.
