GOP presidential hopefuls Marco Rubio and Jeb Bush are campaigning within a few miles of each other in Wisconsin Monday and both are slated to attend events with Republican Gov. Scott Walker, who dropped out of the presidential race on Sept. 21.

Rubio, who has reached out to Walker in recent days, is expected to meet privately with the governor after a 4:30 p.m. reception featuring the Florida senator, according to a person familiar with the candidate's plans. The event at the Veterans Terrace in Burlington, Wis.,  was set up to raise money for state Assembly speaker Robin Vos, who has endorsed Rubio's presidential bid. 

Vos and more than a dozen state legislators have already endorsed Rubio. Those who pay $100 to attend the Burlington event  will have a chance to join Rubio for a general reception while those who pay $500 will get a photo with the Florida senator, according to a copy of the invitation provided to The Washington Post. Supporters willing to part with $2,500 will be invited to a private "roundtable discussion" with Rubio attended by only about two dozen people.

Before attending the Rubio event, Walker plans to join Bush at a joint appearance at a private charter school in Waukesha.
