SALT LAKE CITY (AP) — An adult film star has called on the governor of Utah to veto a bill that would mandate pornography filters on all new cellphones and tablets sold in the state.

Cherie DeVille said in a letter published Saturday in The Daily Beast that the law would violate residents’ First Amendment rights. Those concerns have also been voiced by electronic civil liberties experts.

Republican Gov. Spencer Cox hasn’t said if he’ll sign the bill. He has said it would send an important message about preventing explicit online content from getting to kids.

Supporters say the bill would not violate constitutional rights because adults could turn off the filters.
