The former two-term governor, who directed Maine from 2011-2019, will begin his campaign at a rally at the civic center in Augusta, the state’s capital city.
"I serve you, the everyday working men and women, who pay their taxes, follow the rules and endeavor to always do the right thing," LePage announced in his speech, according to excerpts exclusively shared with Fox News before the former governor’s speech.
And taking aim at Mills, LePage will charge that his successor "inherited a lean, efficient and accountable state government. They proceeded to send Maine backwards."
"Maine continues to struggle under one of the highest overall state and local tax burdens," he'll explain.

LePage, who was first elected governor in 2010 and re elected four years later, was prevented by term limits from attempting a third straight term in 2018. In Maine, a governor can serve an endless number of terms, though just two in a row.

Mills, who as Maine’s attorney general throughout LePage’s tenure steering the state was often at odds with the governor, has not yet announced she’s running for reelection yet has already started fundraising for a second term as governor.

The pugnacious LePage became known both inside Maine and across the nation for stirring controversy thanks to his off-the-cuff comments.

Among them - throughout his first campaign for governor, LePage announced he would tell then-President Obama to "go to hell" if he were elected.
And throughout his second term, LePage stated that out-of-state drug dealers with names like "D-Money, Smoothie, Shifty" sell heroin in Maine and impregnate "young White girl[s]" before they leave.

Though in declaring his 2022 bid in a July statement – which entitled him to start fundraising – LePage dodged any bombastic language, stating that "Maine faces several challenges and we must work toward building a better future based on individual liberty, fiscal responsibility, and an economy which empowers everyone including our rural communities."

And at a fundraiser this summer for a conservative group, LePage acknowledged that "I’ve been a bit controversial in the past."
"Hope to clean up my act this time," he continued.
Brent Littlefield, LePage’s longtime political consultant, is spotlighting what appears to be a more sensitive and gentler LePage.
"LePage does have a history of working across the aisle," Littlefield told Fox News, noting LePage’s two elected terms as mayor of Waterville, Maine, a Democratic city. "He’s looking forward to working with Republicans, Independents and Democrats willing to work together to accomplish his goals and his mission."
