WASHINGTON -- Sen. Bernie Sanders (I-VT) made waves Tuesday morning when he announced he is running for president in 2020 and his campaign with be a grassroots movement that will“lay the groundwork for transforming the economic and political life of this country.”

That message, while vague, appears to be hitting home with supporters as Sanders raised $1 million in the first four hours after announcing the campaign at 7 a.m. EST., according to CBS News. The donations came from all 50 states according to an aide who spoke to CBS.

And while other candidates have raised a similar amount since announcing their campaigns, those totals were typically hit a day or two after the announcements was made. Sanders appears to have already dwarfed the campaign donations of Sen. Kamala Harris (D-CA) and Sen. Amy Klobuchar, (D-MN). The actual total won’t be known until later in 2019 when campaign finance disclosure forms are required to be filed.

Although he didn’t earn the Democratic nomination in 2016, Sanders earned more than 13 million votes and won several primaries and caucuses while running against eventual winner Hilary Clinton. And while he says it’s important that he defeat President Donald Trump in 2020, he says it’s also about changing the country in the long term.

“Our campaign is not only about defeating Donald Trump,” Sanders said in an email to supporters. “Our campaign is about transforming our country and creating a government based on the principles of economic, social, racial and environmental justice.”
