Top advisers to Donald Trump have begun to discuss draft language for the 2024 Republican platform that antiabortion leaders expect will abandon the party’s decades-long call to amend the U.S. Constitution to extend personhood protections to the unborn, according to multiple people involved with the discussions.

The escalating behind-the-scenes disagreement over the abortion language has become so tense and acrimonious in recent weeks that some social conservative leaders have issued public warnings of a coming split within Trump’s coalition. Others have started to discuss an effort to issue a “minority report” to the platform at the convention, according to the people involved, who like others for this story spoke on the condition of anonymity to describe private conversations.
