SIOUX CITY, Iowa (AP) — The superintendent of Sioux City schools says he won’t block plans by Republican presidential candidate Donald Trump to hold an event at a district high school. Superintendent Paul Gausman announced Friday that despite complaints and a threatened protest, he won’t stop Trump from using West High School on Tuesday for a campaign event.

The Sioux City Journal reports a 2012 West High graduate organized a petition calling for the district to not allow use of the school for Trump’s event. He’s now planning a protest at the site. Former student Francisco Valadez says Trump shouldn’t be allowed to use the school because of his views on immigration.

Gausman says many candidates have held events at Sioux City schools, so it’s not fair to exclude Trump.
