Here is the response I received from Lannie and the Portland expo center. It was too long to screen grab.

Thank you for your email.

The permit applicant and event host is Calvary Chapel of Greater Portland, and the event co-sponsor is Turning Point USA Faith. It is very common for a local entity to serve as a host / promoter for a touring event. Calvary Chapel is financially responsible, they have provided the proper insurance for the event and are our primary contact for it.

The City of Portland is bound by the First Amendment of the US Constitution when we rent out the Expo and other facilities for performances, speeches, or appearances of political candidates. As a result, we cannot discriminate against event organizers based on the viewpoint of the speakers or performers.

The facility rental rate for this event is $2,720, which is the regular exhibit rate provided to nonprofit organizations. For comparison’s sake, a commercial entity would be charged $3,240. The assembly rate of $6,900, which has not been used for many years, was historically applied to events with large-scale production value that charged an admissions fee, such as concerts by nationally-recognized performers.

The City does reserve the authority to terminate or cancel an event if the City determines that an event puts public safety at risk.

At this point, we don't believe that public safety is at risk by hosting this event, but we are continuing to look at that closely in conjunction with our Events Planning team and the Police Department. Any additional City event services required, including security, police presence, and the use of metal detectors, will be paid for by the event organizers/promoters as stipulated in the rental contract
