President George W. Bush signed emergency legislation sent to him by Congress early Monday to allow Terri Schiavo's parents to ask a federal judge to prolong their daughter's life, capping days of emotional debate over who should decide life and death. "In cases like this one, where there are serious questions and substantial doubts, our society, our laws and our courts should have a presumption in favor of life," Bush said in a statement after signing the bill. After flying back to Washington from his Texas ranch, Bush had waited at the White House to sign the measure permitting a federal review of the case, which could trigger the reinsertion of feeding tubes needed to keep the brain-damaged Florida woman alive. The House passed the bill on a 203-58 vote early Monday after calling lawmakers back for an emergency Sunday session for debate that stretched past midnight. The measure was backed by 156 Republicans to 5 who voted against it and 71 who did not vote; 47 Democrats voted in favor, 53 against and 102 did not vote. The lone independent in the 435 member house did not vote. The Senate approved the bill Sunday by voice vote.
