House Speaker Paul Ryan will campaign with Donald Trump for the first time this year at an event in Wisconsin on Saturday.

Trump and Ryan will appear together at Fall Fest at the Walworth County Fairgrounds in southeast Wisconsin. They will also be joined by Gov. Scott Walker and Sen. Ron Johnson, who is facing a tough general election fight, at an event slated for 2:30 p.m. EST.

The campaign stop will also come one day before Trump is set to take the stage in the second presidential debate.

According to a source familiar with the plans, Trump expressed interest in holding an event with Ryan and ultimately accepted an invitation to Fall Fest, which is held in the state's first congressional district, which Ryan represents.

Ryan announced in early June that he would vote for the GOP nominee, after he initially said he wasn't ready to do so. The two met over the course of the summer, including a high-profile meet at the Republican National Committee, and according to New York Magazine, Ryan and Trump speak "maybe every two weeks."
