A family in suburban Boston hopes to change the phrasing of the Pledge of Allegiance to remove two words they claim violate students’ rights.

The family is challenging the pledge, which students recite daily in U.S. public schools, claiming the words “under God” violate the state’s equal rights laws.

The plaintiffs, who have requested anonymity through their lawyers, are taking an unconventional approach to challenging the pledge. Past cases argued the words “under God” violated the Constitution’s separation of church and state.
