WASHINGTON - President Donald Trump promised Wednesday to sign an executive order that would require health care providers to provide medical care to all babies born alive as he makes an election-year push to appeal to voters who oppose abortion.The White House did not release further details about the order, but Trump’s announcement follows numerous attempts by GOP lawmakers in Washington and in state capitals around the country to pass legislation that threatens prison for doctors who don’t try to save the life of infants born alive during abortions.Organizations representing obstetricians and gynecologists say the law already provides protections to newborns, whether born during a failed abortion or under other circumstances.
