Republican presidential candidate Donald Trump will hold a campaign rally at the Northwest Washington Fairgrounds in Lynden on Saturday, May 7, Lynden Mayor Scott Korthuis confirmed. Korthuis said the contract for the venue was signed after 9 p.m. Thursday, May 5.

“Normally when we have an event of this magnitude, we have several weeks to prepare,” said Whatcom Sheriff Bill Elfo.

Authorities will be working “diligently” to prepare for the event with the U.S. Secret Service on “very short notice,” he added.

Sen. Doug Ericksen, R-Ferndale, said the event will be scheduled for 3 p.m. Ericksen is part of Trump’s state campaign team.

“Our goal is to have one event in Spokane, and one on the west side, which in all likelihood will be in Lynden, but we are waiting for that contract to be finalized,” Ericksen said Thursday afternoon.

“The Northwest Washington Fair is a non-profit organization that routinely rents space to outside organizations as part of our business operation. Last year, we rented space for more than 100 events held by outside organizations,” said Jim Baron, general manager at the fairgrounds in Lynden. “When we rent space to a political party or candidate, it is in no way an endorsement but simply a business transaction.”

The event will be scheduled for the main grandstand outdoors.
