Bernie Sanders' campaign says it's reached 4 million donors

In the third quarter, Sanders outraised his Democratic opponents, raking in $25.3 million

Bernie Sanders' presidential campaign announced Tuesday that it has received donations from more than 4 million individual donations.

"This is what momentum looks like," Faiz Shakir, Sanders' campaign manager, said in a statement.

During the 2016 presidential election, Sanders did not receive 4 million individual campaign donations until after the New Hampshire primary, which took place at the beginning of February, his campaign said.

In the third quarter, Sanders out-fundraised all of his Democratic opponents, raking in $25.3 million. He was followed by Massachusetts Sen. Elizabeth Warren, his progressive rival who's also eschewed big-money fundraisers. Warren netted $24.6 million in the third quarter.

In the third quarter, Biden raised $15.2 million, while Buttigieg raised $19.1 million.
