Warren posted an ActBlue link Saturday on X in support of two California charities but soon received a Community Note saying it “is not a link to charity. It is a link to a Democrat fundraising platform.”

When clicked, the link leads to a page with “Warren for Senate” at the top with descriptions of two charities, the Los Angeles Fire Department Foundation and the United Way of Greater Los Angeles, below.

“Your full donation will directly support these two organizations,” the page says.

Donations are in increments of $5, $15, $28, $50, $100, $250, and $500. The $28 amount appears to be a reference to the 2028 presidential election.

The commenters also pointed out that ActBlue collects a 3.95% processing charge on every transaction.

The donation is processed via ActBlue’s charity arm, ActBlue Charities. Warren does not appear to be reaping financial benefits directly from each donation, but visitors to the page can click through to her Senate campaign page, where they can donate directly to her.

ActBlue also collects the information of every person who donates, allowing the platform to later use data to provide “information, tips, and offers about ActBlue services.”

Republicans blasted Warren for her choice to use the platform to raise money for charity.

“Just when I think ‘my’ Senator can’t sink any lower she tries to loot well-meaning donors that want to help California fire victims,” Cecilia Calabrese, director of Mass For Trump in Region 3, posted on X. “ActBlue is a Democrat fundraiser platform only. Shame on you, Senator, for pushing this scam!”

Chester Tam, a Massachusetts Republican National Convention delegate and vice chairman of operations and digital media for Trump in Massachusetts, also slammed Warren.

“Donating through the Warren for Senate campaign site is the last thing you should do if you want to support efforts for the California fires,” he posted on X. “How much of that money do you think will end up benefitting Warren’s campaign? Once again Democrats exploit a disaster for their own gain.”

Gov. Gavin Newsom (D-CA) also used ActBlue to raise money for the California Fire Foundation, which provides emotional and financial assistance to families of fallen firefighters, firefighters, and the communities they serve.

ActBlue is also under fire for continuing to accept monthly donations for Vice President Kamala Harris’s 2024 failed presidential campaign. If subscribers don’t turn off their monthly donations, they will continue contributing to her campaign even if they don’t wish to.
