David Muir is a well-respected journalist and has been with ABC since 2003, where he's made an incredible impact in the past two decades.
This has included hosting World News Tonight since 2014, taking over from Diane Sawyer, and hosting 20/20 since 2013.
His current 20/20 co-anchor is Deborah Roberts, and he's not only close with her, but her husband, Al Roker too.

Al took to Instagram to post a photo of David on the red carpet at a previous Time 100 event, and wrote: "Congratulations to @davidmuirabc on being named one of the @time 100."
Fans were quick to follow Al with their messages of support and congratulations, with one writing in the comments: "Well deserved David," while another wrote: "David is just wonderful." A third added: "He is the best of the best."
Al wasn't the only famous face to pay tribute to David. Diane Sawyer, who he took over World News Tonight from back in 2014, also paid her respects to the broadcaster.

"David Muir anchors the nation's most-watched television news program, ABC World News Tonight," Diane, 79, continued. "Every night more than 8 million Americans trust him to make sense of the day."

He traveled days to hold the hands of starving children in Madagascar and South Sudan, leading to millions of dollars in donations to the World Food Programme.
"I think I know what destiny looks like because I've seen a photo of a serious 13-year-old boy, talking his way into an internship at the local TV station. Now he's the anchor chosen for interviews by Popes and Presidents. He shows up calm, respectful, and fearless."

She wrote: "I am lucky that my successor is also the irreverent friend I want to hang out with when the camera shuts down," ending on a comedic note with: "Though I am also miffed that he's the guy who can leap two flights of stairs, vault into the anchor chair, and never lose focus – or his breath."
World News Tonight is the No.1 most watched television program across broadcast. David has been joined by a long list of famous honorees, including Serena Williams, Demi Moore and Snoop Dogg.
