"I will always be President-elect Trump's biggest supporter," Lewandowski said in the news release. "After considering multiple opportunities within the administration, I informed him and his team I think I can best help him outside the formal structure of the government. I very much look forward to doing that every day."
The group's stated goal is to "ensure the president-elect's agenda is achieved."
It will be located at 1717 Pennsylvania Avenue, right down the street from the White House.
Politico reported Tuesday that Lewandowski was not expected to be included in the first wave of White House jobs.
Lewandowski was originally let go by the Trump campaign after it went into a tailspin in early June, following a lengthy power struggle with then-Trump campaign chair Paul Manafort, as well as a controversy surrounding his grabbing of a then-Breitbart News reporter at a Trump event.
