A left-wing meme factory aimed at combating Trump’s alternative facts was slapped with a hack attack Sunday after garnering an endorsement from Hillary Clinton.

Starter founder and Democratic operative Peter Daou said his website, Verrit, went offline because of a suspected distributed denial-of-service attack following the former presidential candidate’s glowing review.

"Hillary Clinton endorsed @Verrit, our new media platform, an hour ago and we've already been subjected to a denial-of-service attack," Daou tweeted. "We're working on restoring it ASAP."

The website was not working as of 10:30 p.m. Sunday.

He later complained that he had received a "torrent of Hillary hate" following the pol plug.

Daou, who previously worked for Clinton’s senate campaign and first White House bid, said his media site caters to the 65.8 million who voted for Clinton.

He said it would feature graphics with "rigorously-verified info," without elaborating on how or who would be fact-checking the work, that can be circulated on social media platforms.

A sampling of the Verrit cards shared by Daou on Sunday were quotes from Clinton, former Presidents John F. Kennedy and Dwight Eisenhower.
