Kobach said Thursday that his campaign treasurer, state Rep. Tom Arpke of Salina, is not responsible for the mistakes and actually helped find them. Arpke did not immediately return a telephone message seeking comment.
The ethics commission has set an Oct. 26 hearing on whether Arpke should be fined. Kansas law makes a campaign treasurer responsible for mistakes on reports.
Commission Executive Director Carol Williams said Kobach’s campaign omitted $35,000 worth of contributions and $42,000 worth of expenditures from reports in 2010.
Kobach said his campaign reviewed its books after the election to ensure its reports were complete.
