Bush backs Romney for president

\"I\'m for Mitt Romney,\" ex-president George W. Bush told ABC Tuesday, throwing his support behind the likely Republican nominee to challenge President Barack Obama in November elections. Bush made the remark early Tuesday as elevator doors were closing behind him, ABC said on its blog. The former president has made few media appearances during the Republican primary campaign, but his support for Romney was not a surprise. The candidate had already received the backing of the elder George H. Bush, president from 1989 to 1993, in March. George W. Bush was visiting Washington Tuesday to speak about human rights. Since leaving the White House in January 2009, Bush has generally refrained from criticizing his successor. In 2010, Bush published his presidential memoirs titled \"Decision Points.\" He is not due to campaign for Romney, ABC said.
