From the JOURNAL SENTINEL:
Americans for Prosperity, a political action group financed by the billionaire Koch brothers, has been active in supporting Gov. Scott Walker and his budget-repair bill.
AFP director Tim Phillips said Monday that his group already had spent $400,000 on TV and radio ads in the state in support of the governor.
“Yes, we will continue to be very active,” Phillips said.
Phillips said his group’s efforts began in Wisconsin in January 2005.
