Brad Pitt's mother attacks Barack Obama on gay marriage While her son is a champion of gay rights, Jane Pitt has thrown her support behind the Republican candidate Mitt Romney, attacking Mr Obama for his liberal views on abortion, same-sex marriage and his links to the firebrand pastor Jeremiah Wright. Calling on Christian voters to accept Mr Romney - who is a Mormon - Mrs Pitt said she would be happy to for a "family man with high morals" who shares "Christian conviction" on homosexuality over the likes of Mr Obama. "Any Christian who does not vote or writes in a name is casting a vote for Romney's opponent, Barack Hussein Obama - a man who sat in Jeremiah Wright's church for years, did not hold a public ceremony to mark the National Day of Prayer, and is a liberal who supports the killing of unborn babies and same-sex marriage," she wrote in Missouri's Springfield News-Leader. Mrs Pitt's attack on the president came as one of his most prominent Hollywood backers, the Oscar-winning actor Morgan Freeman, said that Mr Obama was not the first black president of the United States. In an interview attacking Republicans for the partisan refusal to do business with the Obama administration, Freeman said those who opposed the president because he was "black" should realise he was mixed-race. "First thing that always pops into my head regarding our president is that all of the people who are setting up this barrier for him ... they just conveniently forget that Barack had a mama, and she was white ... very white American, Kansas, middle of America," Freeman told National Public Radio. There was no argument about who he is or what he is. America's first black president hasn't arisen yet. He's not America's first black president ... he's America's first mixed-race president.
