on august 1, 2019, kobach sent out a campaign fundraiser using both the corporate name and email list of "wall" donors. common cause vice president for policy and litigation paul s. ryan said, "at a minimum, this kobach for senate fundraising solicitation email appears to violate the 'paid for by' disclaimer requirement" for official campaign communications. ryan specified the requirement that mandates disclosure of the financial sponsors who originate official political communications. kobach's email might be legal if his campaign paid fair market value for use of the list. if that were the case, a "paid for by" disclaimer would be required but was not present in the solicitation. ryan said, "if the kobach committee did not pay fair market value for the cost of disseminating this email, then the committee has arguably committed the more serious campaign finance law violation of receiving a corporate contribution in the form of a coordinated expenditure." we build the wall is legally prohibited from financing federal political campaigns in any fashion. besides the concerns raised about kolfage himself, a week prior to the mailer, right-wing anti-immigrant, "wall" board member and former congressman tom tancredo sat on the stage alongside kobach, and endorsed him in a new mexico rally pushing the wall.
