Students at Westminster High School will rally Friday against the school system's decision to ban "We the People" posters in classrooms.
School officials said the posters were anti-Trump and violated policies banning educators from taking political positions in the classroom.
The posters depict racially diverse women in the red, white and blue motif used in former President Barack Obama's 2008 campaign.
The "We the People" posters were used during the Women's March in January.
Students wore T-shirts with the banned images to school on Wednesday after raising around $5,000 to make the T-shirts using a GoFundMe page.
Students were evacuated from the school Wednesday after Westminster High School received a bomb threat. School officials are investigating a possible connection with students printing T-shirts of the banned images.
The Rally for Diversity will starts at 3 p.m. Friday in front of the Carroll County Board of Education building, located at 125 N Court St. in Westminster.
