Barack Obama

PANAMA CITY (AP) — President Barack Obama said Saturday that partisan wrangling over the emerging nuclear agreement with Iran and on other foreign policy matters has gone beyond the pale, singling out two senior Republican senators for particularly harsh criticism. "It needs to stop," he declared.

Obama complained that Sen. John McCain of Arizona had suggested that U.S. Secretary of State John Kerry's explanations of the framework agreement with Iran were "somehow less trustworthy" than those of Iran's supreme leader.

"That's an indication of the degree to which partisanship has crossed all boundaries," an exercised Obama said in a news conference at the end of the two-day Summit of the Americas. "And we're seeing this again and again."
