WASHINGTON (AP) — Still grappling with Donald Trump's surprise election, the nation's business community has begun to pressure the president-elect to abandon campaign-trail pledges of mass deportation and other hardline immigration policies that some large employers fear would hurt the economy. The push, led by an advocacy group backed by New York billionaire Michael Bloomberg and media mogul Rupert Murdoch, is still in its infancy as the business world struggles to understand the tough-talking Trump's true intentions on an issue that defined his outsider campaign. [...] others are assembling teams of public officials and industry leaders on the ground in key states to encourage Trump to embrace a more forgiving immigration policy — in the name of economic development, if not human compassion. Trump railed against the dangers of illegal immigration throughout his campaign, several times sharing the stage with parents of children killed by immigrants in the country illegally. "Donald Trump will lose all credibility," said Dan Stein, president of the Federation for American Immigration Reform, a group that pushes for strict immigration policies.
