WASHINGTON (Reuters) - U.S. President Donald Trump said in a tweet on Monday that he would announce his decision on whether to withdraw from the Iran nuclear deal at 2:00 p.m. EDT on Tuesday.

Trump has threatened to withdraw from the deal, which provided Iran with relief from sanctions in exchange for limiting its uranium enrichment capacity, unless European signatories to the accord fix what he has called its shortcomings.
