US President Donald Trump says he's made his decision on the Iran nuclear deal - and, will reveal it Tuesday afternoon. Trump has repeatedly threatened to withdraw from the deal -- unless France, Germany and Britain fix what he labels as flaws. The 2015 deal saw the easing of economic sanctions on Iran in exchange for Tehran limiting its nuclear program. A senior US official said it was unclear if efforts by European allies to address Trump's concerns would be enough to save the pact. White House correspondent Nathan King reports.
