Elon Musk’s super PAC spent around $200 million to help elect Donald Trump, according to a person familiar with the group’s spending, funding an effort that set a new standard for how billionaires can influence elections, AP reports.

The billionaire Tesla and SpaceX CEO provided the vast majority of the money to America PAC, which focused on low-propensity and first-time voters, according to the person, who was not authorized to disclose the figure publicly and spoke on condition of anonymity.

America PAC’s work was aided by a March ruling from the Federal Election Commission that paved the way for super PACs to coordinate their canvassing efforts with campaigns, allowing the Trump campaign to rely on the near-unlimited money of the nation’s most high-profile billionaire to boost turnout in deep-red parts of the country. That allowed the campaign to spend the money they saved on everything from national ad campaigns to targeted outreach toward demographics Democrats once dominated.
