Sen. Bernie Sanders (I-Vt.) has raised more than $18.2 million since launching his 2020 presidential campaign in late February, the campaign announced on Tuesday.

Sanders raised that sum from nearly 900,000 contributions, which came from 525,000 individuals, some of whom donated more than once. The average donation was $20, and 99.5 percent of donations were in increments of $100 or less.

But Sanders, who handily won re-election to the Senate in November, also benefits from transferring outstanding funds from previous campaign accounts to his presidential run.

Counting those funds, Sanders has raised $32 million and has $28 million in cash on hand that he can still spend.

The state of the Bernie Sanders campaign is strong and getting stronger by the day, said campaign manager Faiz Shakir on a call with reporters announcing the figures.
