The presidential campaign of Sen. Marco Rubio has called off a Minneapolis fundraiser planned for Thursday because the Florida Republican needs to be in Washington to vote on the Iran nuclear deal. 

Rubio spokesman Alex Conant confirmed late Wednesday that the Minneapolis Club fundraiser was off. A U.S. Senate vote on the deal struck between the Obama Administration, Iran and other nations was initially expected to come at the end of the week but is now expected on Thursday. 

Conant said the fundraiser would be rescheduled. Another Republican presidential candidate, New Jersey Gov. Chris Christie, is also scheduled for a Minneapolis fundraising stop on Thursday.
