Donald Trump has begun spending money on television ads in Wisconsin.
Trump's campaign had not spent anything on ads in the state until this week. Kantar Media's political ad tracker showed Wednesday that Trump has reserved about $600,000 in airtime over the next few weeks.
Democrat Hillary Clinton has yet to spend any money on ads in Wisconsin or campaign in the state.
Trump is slated to return to Wisconsin on Monday. He had planned to attend a Republican unity rally in southeast Wisconsin last weekend, but House Speaker Paul Ryan revoked the invitation.
Ryan has since said he will no longer defend or campaign with Trump in the wake of Trump's predatory and crude comments about women. But Ryan has not pulled his support for Trump.
