One of the U.S. political ads found by CBS News was under a post by a verified account that prolifically posts pro-Nazi and racist content. The account, which has nearly 100,000 followers, shared a picture of Hitler rejecting a Star of David being held by an arm draped in a striped sleeve.
Under the post, an ad appeared for the National Republican Senatorial Committee directing users to donate through WinRed, the prominent conservative online fundraising platform used by many GOP candidates and groups, including GOP presidential candidate Donald Trump's campaign and the Republican National Committee.
The advertisement showed an image of Florida Sen. Marco Rubio with the caption saying it was "paid for by the NRSC."
The NRSC is the chief fundraising committee dedicated to getting Republican Party candidates elected to the U.S. Senate. Multiple other promoted advertisements directing users to WinRed were posted under similar content. CBS News is not publicly identifying the accounts spreading racist content on X.
CBS News asked the NRSC and WinRed for comment about the placement of the fundraising ads on X. In response to questions about the ads on X, NRSC spokesman Mike Berg wrote in a post on the platform that CBS News was, "trying to pressure advertisers to stop spending money on X by associating advertisers and [Musk] with white nationalists," which he called "patently absurd."
Promoted advertisements for the congressional campaign of Jerrad Christan, the Democratic candidate for Ohio's 12th district, also appeared under antisemitic posts. The seat is currently held by Republican Troy Balderson.
