EXCLUSIVE FOX NEWS REPORT: Former Rep. Devin Nunes is sharing new details about TRUTH Social and his decision to leave Congress to take on Big Tech as the CEO of Trump Media & Technology Group, vowing to create the "free-est" social media platform for users across the United States and around the world. 

In an exclusive interview with Fox News, his first since retiring from Congress after nearly two decades representing California's 22nd Congressional District, and after leading the House Intelligence Committee for nearly a decade, Nunes said his new chapter is "not political" but instead a continuation of his public service.

"I still see what I am doing as a public service. It is not political, but it is public service," Nunes told Fox News. "This has to be done. This is the most important issue at the highest level."

"It is really serious what we're doing," he continued. "Millions of Americans and people around the globe are counting on us to get this done and get it done right."

Nunes announced his resignation from Congress in December, and soon after was named by former President Trump to be CEO of Trump Media & Technology Group (TMTG).

Nunes said the move shouldn't come as a surprise, telling Fox News that he has been sounding the alarm on Big Tech suppression and disinformation for the last several years. 

"It was hard for me to say no because it is the issue I have been most passionate about over the last few years," Nunes said. "You would have to be hiding under a rock to not know my frustration with these Big Tech companies." 

Nunes said he has "always flirted with technology," noting he was one of the first in Congress to send text messages to constituents, beginning as early as 2009. Nunes also developed the digital arm of the National Republican Congressional Committee. 

Nunes recalled that he was one of the first elected officials to transition to Rumble – an alternative video platform to YouTube. TMTG last month announced a cloud services partnership with Rumble.
