Within hours of the unveiling on Tuesday of a nuclear pact between Iran and six world powers, the loudest pro-Israel voice in Washington was warning the US Congress of problems, marking the onset of what promises to be a furious lobbying campaign.
The American Israel Public Affairs Committee said in a statement it was "deeply concerned" over the deal, Reuters reported.
The considerable clout of pro-Israel interests on Capitol Hill will play an important role in deciding the fate of the pact.
Congressional votes on the deal, which got a rough initial reception from Republican lawmakers, were not expected until September. Regardless of Israeli lobbying, however, odds were slim that US lawmakers would be able to derail the deal.
