ABERDEEN, S.D. (AP) — Barack Obama has resigned his 20 year membership in the Trinity United Church of Christ in Chicago in the aftermath of inflammatory remarks by his longtime pastor the Rev. Jeremiah Wright and more recent fiery remarks at the church by another minister.

Obama campaign communications director Robert Gibbs said Obama had submitted a letter of resignation to the church and would discuss his decision in a session with reporters later Saturday.

It happened "over the last few days," Gibbs said.

Comments by Wright have inflamed racial tensions and posed an unwanted problem for Obama, front-runner for the Democratic presidential nomination, as he seeks to wrap up the nomination.

More recently, racially charged remarks from the same pulpit by another pastor, the Rev. Michael Pfleger, has kept the controversy alive and proved the latest thorn in the side of Obama.

Pfleger earlier this month mocked Obama rival Hillary Rodham Clinton as a guest speaker at Obama's church.

Obama has condemned comments by both Wright and Pfleger, but the controversy has persisted.
