Hundreds of Oregon high school students walked out of class Thursday to protest a banner that made reference to Donald Trump's plan for a wall along the U.S. border with Mexico.
A sign reading "build a wall" appeared briefly in a cafeteria Wednesday at Forest Grove High School in suburban Portland. School officials quickly removed it.
Students who protested Thursday morning marched down a street before eventually returning to school. Some students from other Oregon high schools joined the demonstration.
The Forest Grove district has the highest percentage of Latino students in the Portland area. Officials said the students responsible for the banner were disciplined.
Trump, the presumptive Republican presidential nominee, has said he wants to clamp down on illegal immigration and for Mexico to pay for a border wall.
