from AP: Relations between President Barack Obama and U.S. corporate leaders have grown tense in recent weeks, with business groups bristling over his sharp rebukes of lenders and multinational companies in particular. Executives and trade groups that praised Obama's outreach during his post-election transition period say they have felt less welcome since he took office in January. More troubling, they say, are his populist-tinged, sometimes acid critiques of certain sectors, including large companies that keep some profits overseas to reduce their U.S. tax burden.
