Ziklag and the Courage Tour, the far-right groups that hosted the Republican vice-presidential nominee, are charities that can’t legally intervene in political campaigns.

Republican vice-presidential nominee JD Vance’s appearance at a far-right Christian revival tour last month may have broken tax and election laws, experts say.

On Sept. 28, Vance held an official campaign event in Monroeville, Pennsylvania, in partnership with the Courage Tour, a series of swing-state rallies hosted by a pro-Trump Christian influencer that combine prayer, public speakers, tutorials on how to become a poll worker and get-out-the-vote programming.

Even before the Vance event, ProPublica previously reported that tax experts believed Ziklag’s 2024 election-related efforts could be in violation of tax law. The Vance event, they said, raised even more red flags about whether a tax-exempt charity had improperly benefited the Trump-Vance campaign.
