Almost five years later, Tim Russert's death is still hard for Tom Brokaw to talk about.
The legendary NBC News journalist visited HuffPost Live Thursday and choked up when host Alicia Menendez asked him about the day Russert died.
"My world kind of blew up in front of me," Brokaw said of the moment he learned that Russert had died.
Russert, the moderator of NBC's "Meet The Press" as well as NBC's Washington Bureau Chief, collapsed and died in the newsroom in 2008. Brokaw broke the news in a special report that afternoon, and delivered a moving speech at Russert's memorial service the following week.
