A group of African-American religious leaders are calling on black voters to turn their backs on President Barack Obama over his endorsement of gay marriage.

Obama announced his support in May.

The group God Said has pledged $1 million for an ad campaign opposing the president's stance and calling on black voters to vote against politicians who support marriage equality.

“The black community is among the most religious in America,” Apostle Claver Kamau-Imani, the group's founder, said in a statement. “We are offended that President Obama has announced his support of same-sex marriage, that the NAACP has blindly supported the secular views of the Democratic Party and that their national platform plainly supports same-sex marriage. I am confident this message will be well received and acted upon on Election Day.”

The executive board of God Said includes former Miss America contestant Day Gardner and Alveda King, the niece of Dr. Martin Luther King.

“During the 2008 elections, 70 percent of African-Americans voted to ban same-sex marriage in California while they also voted for Barack Obama for president,” King told The Daily Caller. “We fully intend to shift 25 percent of the black vote from the 2008 election by charging every voter to examine each candidate and vote for the one that supports their core belief in natural marriage.”

A video on the group's website calls on voters to “vote His values.” (The video is embedded on this page. Visit our video library for more videos.)
