President Joe Biden went to church on Saturday in his hometown a day after US Roman Catholic bishops issued a challenge to him over his support for abortion rights.

Biden and first lady Jill Biden spent time at St Joseph on the Brandywine church in Wilmington. They also visited the church graveyard where the president's first wife Neilia, son Beau and infant daughter Naomi are buried.

Biden, 78, is a devout Catholic who attends mass at least once a week, and he supports the landmark 1973 US Supreme Court decision affirming a woman's right to an abortion.

On Friday US bishops agreed to draft a statement on the meaning of holy communion which could potentially be used to deny that sacrament to the American leader.

The eucharist, also known as holy communion, is among the most sacred rituals in the Catholic Church and there have been calls from some conservative church leaders to deny the sacrament to politicians who support abortion rights.
