It was a reunion of sorts at the Newseum in downtown Washington, as former Washington Post editor Ben Bradlee, 91, and Bernstein greeted each other with a kiss on the cheek. The pair walked with arms behind each other’s backs as they posed for a photo with Woodward and Discovery Channel executives.

During a question and answer session with Fox News Channel journalist and WHCA President Ed Henry, Bernstein touched upon the rise of tweeting and journalism in the digital age, saying of reporting, “It takes place at night, in darkness. We go out, knock on a lot of doors. We use common sense. Nothing glamorous about it. Tweeting is not going to replace that.”

The 69-year-old scribe added, “I’m thinking, well who’s going to knock on doors at night and find out what the hell is really going on? You’re not going to do that tweeting.”

Bradlee, Woodward, and Bernstein sat alongside each another during the screening, which led Bloomberg Media Group CEO Andy Lack to crack that the seating arrangement was the “murderers' row of journalism.”

Woodward, 70, was eyed whispering something in Bernstein’s ear at one point during the documentary. The duo chuckled at a moment in the Discovery special when Alexander Butterfield, the former deputy assistant to Nixon who confirmed the existence of the president’s secret White House tapes, did an impression of the ex-commander-in-chief.
