WASHINGTON (AP) — Bernie Sanders’ campaign says he has raised more than $4 million in the 12 hours since announcing his 2020 presidential campaign.

The Vermont senator said Tuesday that nearly 150,000 individuals had contributed to his Democratic bid.

Previously, the biggest first-day fundraiser in the race had been California Sen. Kamala Harris, who raised $1.5 million in the first 24 hours of her campaign.
