BOSTON (AP) — Possible Republican presidential contender Rick Santorum is headlining a benefit for a Massachusetts Catholic group.

The former two-term senator from Pennsylvania will address members of Catholic Citizenship on Tuesday in Newton.

Santorum is a favorite of conservatives for his staunch opposition to abortion rights, which the Roman Catholic church also opposes.

He now is a senior fellow at the Ethics and Public Policy Center in Washington, D.C., which focuses on the Judeo-Christian moral tradition within the debate over domestic and foreign policy issues. He also is a frequent contributor on Fox News Channel.

Santorum is among a group of Republicans weighing a 2012 presidential run. They include former Massachusetts Gov. Mitt Romney.
