Questions over the logistics surrounding President Donald Trump's campaign speech in Missoula were answered in part on Wednesday evening, at least when it comes to parking.

Trump is set to speak in support of U.S. Senate candidate Matt Rosendale at 6:30 p.m. on Thursday at Missoula International Airport, and promote his own successes in office. Rosendale is challenging incumbent Sen. Jon Tester for his seat in Congress.

Thursday's venue was originally scheduled for Neptune Aviation, though that was quickly changed to the Minuteman aviation hangar earlier this week. The confusion ensued from there, and no details on capacity or seating have been released.

But airport officials, working with U.S. Secret Service, attempted to clarify the parking situation on Wednesday evening, saying it won't be permitted on airport property.

“It will be east of Northstar (Aviation) off Corporate Way,” said Brian Ellestad, deputy airport director. “What we know right now is that people need to park in that area and everyone attending the function needs to ride a shuttle. They will start staffing that area early afternoon.”

Ellestad said shuttles for the remote parking area will start at 2 p.m.. Attendees are asked not to park in front of the airport's passenger terminal unless they're picking up or dropping off passengers.
