Tom Brokaw, Brian Williams and Kate Couric were among the television journalists remembering Tim Russert, who died at age 58 of coronary artery disease.

"Tim was a big teddy bear of a guy, but he was also a pit bull of an interviewer," says Couric. "He always held people's feet to the fire, often using their past words with great effect to reveal flip-flops or hypocrisy. While Tim was incredibly tenacious, he always did his job with great humanity and respect."
