COLUMBUS, Ohio (AP) — Ohio’s top lawyer has advised the state’s public universities that a law written to deter Ku Klux Klan demonstrations could be used to impose felony charges on students who wear face coverings while protesting the war in Gaza.

In a letter sent Monday, after weeks of pro-Palestinian campus protests around the country, Republican Attorney General Dave Yost advised the presidents of Ohio’s 34 public, four-year universities — which his office represents — to forewarn students about the 1953 law.

“In our society, there are few more significant career-wreckers than a felony charge,” the letter said. “I write to you today to inform your student bodies of an Ohio law that, in the context of some behavior during the recent pro-Palestinian protests, could have that effect.”

The law is contained in a single sentence: “No person shall unite with two or more others to commit a misdemeanor while wearing white caps, masks, or other disguise.” Violating this “anti-disguise” law is punishable by a fourth-degree felony charge, up to $5,000 in fines and five years on community control, Yost wrote.
