JANESVILLE — For the second time in as many months, the possibility of a joint Paul Ryan-Donald Trump campaign appearance was floated and quickly yanked away.

The Republican presidential nominee earlier this week scheduled a Sunday afternoon rally in West Allis, just outside Milwaukee. It was to be Trump's sixth Wisconsin event since he lost the state's primary election to Texas Sen. Ted Cruz.

"We don't know if it's scheduled firm or not yet, but I intend to do it if he's here," Ryan told reporters Saturday when asked if he would attend the Trump rally. "Here's the point: we're going from here to Mukwonago to go campaign with Mike Pence. So everybody's schedule is a little bit in flux in these closing moments, but if our nominee comes, we'll campaign with him."

Seconds later, a spokesman for Trump's Wisconsin campaign alerted reporters that the event had been canceled, citing a scheduling conflict.

Trump has made a strong play for Wisconsin, despite the fact that the state has not gone for a Republican candidate since Ronald Reagan in 1984.

He trails Clinton by six points among likely voters in the Badger State, according to a Marquette University Law School poll released Wednesday.
