David Muir delighted fans with a rare social media message over the July 4th weekend when he shared photos of his latest antics.

The World News Tonight host gave a glimpse into his work life with a series of photos from his recent travels.

In many, David looked cool and casual, ditching his signature suit and tie for a t-shirt and jeans as he filmed a TV special.

“The office these last few weeks,” he wrote. “I’m so grateful to our small army of producers, photographers, editors, true artists – American the Beautiful for sure.”

The post included photos of David interviewing musician Brandi Carlile in front of the Statue of Liberty for the July 4 24-hour ABC special.The ABC News anchor took on a slew of tasks around the country with his colleagues to celebrate the nation’s 250th birthday.

David has always been passionate about his work as a journalist, and ever since he was a young boy, he dreamed of becoming an anchor.

“I was a total nerd,” he admitted during an appearance on LIVE! with his good friend, Kelly Ripa. “In the backyard, everyone was playing. And I’d be out there too, but then I’d be like, ‘I gotta go inside, it’s time for the news!’ So I’d go in and watch the news.”

He recalled then that his drive and ambition was strong even in his early teens, revealing that he’d started visiting a local TV station soon after and even began interning there, a really early start.

“I started visiting the station at 13 years old, I started interning at 14,” he shared. “Obviously, my dad and my mom would take me, so I’m grateful to them.”

“And I’m grateful to everybody in that newsroom because, this is what we all have to remember, this was just a kid with a dream, and they let me show up. And there was a new news director, I got in when there was no boss. That was the only reason a kid at that age could get in.”

“They convinced the new boss to let me keep coming, so I’m grateful to them. And I always try to remember that, when people write to us or reach out to us,” he concluded.

David grew up interning and working with local news stations in his native Syracuse, anchoring the college news program at Ithaca College. He graduated with a journalism degree in 1995.

He was a full-time reporter for WTVH-TV from 1994-2000, and worked for three years after with the ABC-owned WCVB before joining ABC News full-time in 2003.
