MISSOULA (AP) — President Donald Trump’s visit to Missoula this week to campaign on behalf of Republican U.S. Senate candidate Matt Rosendale will be held at Missoula International Airport.

Trump’s campaign initially said the rally would be held at Neptune Aviation Services at 6:30 p.m. Thursday. Organizers decided Monday to moved it to Minuteman Aviation so the president could be photographed speaking in front of Air Force One.

Tickets are available at www.donaldjtrump.com . Attendance is on a first-come, first-serve basis.

This will be the president’s third trip to Montana to campaign on behalf of Rosendale, who seeks to unseat Democratic U.S. Sen. Jon Tester.

Trump appeared in Great Falls in July 5 and in Billings on Sept. 6. Vice President Mike Pence and Donald Trump Jr. have also made trips to the Big Sky State on Rosendale’s behalf.
