(Radio Iowa) — Iowa State University has reached a settlement with a group that accused the school of trying to suppress free speech on campus. Speech First sued the university challenging the school’s ban on chalking political messages on sidewalks, the sending of e-mails for campaigns and elections, and the use of the I-S-U Campus Climate Reporting System.

Speech First president Nicole Neily says they dropped the lawsuit after the university agreed to changes in the policy for chalking and emails. She says the school’s Campus Climate Reporting System will also not contact or meet with students accused of “biased” speech.

I-S-U president Wendy Wintersteen issued a statement that says “the allegations of suppression made by Speech First were simply not true.” Wintersteen says no money was paid to Speech First by Iowa State University.
