A top nonpartisan political crowdfunding site on Tuesday cut ties with its CEO, a Fox News weekend host, and temporarily suspended all fundraising on its platform for Republican candidates.

In a Medium.com post, entitled “A stand against Trumpism, a stand for democracy,” Crowdpac, a for-profit website that helps candidates raise money online, announced a series of major changes including the departure of founder and CEO Steve Hilton, acknowledging that his vocal advocacy for President Donald Trump “created a tension within our platform and community.”

“We’ve heard from many quarters of the Crowdpac community that, in light of Steve Hilton’s political profile, the use of our platform is seen as an endorsement of President Trump and his political movement,” acting CEO Jesse Thomas wrote.
