Iran nuclear deal
Trump is so focused on the Islamic Republic that he reportedly kept a document about it that he knew was classified after he left office. With global concern mounting over Iran's nuclear program, his volatility poses serious risk.
A U.S. return to the deal would be the biggest and most controversial foreign policy initiative in the early months of Joe Biden's presidency.
The decision serves as pressure ahead of the inauguration of President-elect Joe Biden, who has said he is willing to re-enter the Iran nuclear deal.
Any work at the Fordo facility likely will trigger new concern in the waning days of the Trump administration.
WHAT'S HAPPENING
Iranian officials had downplayed the fire, which could set back the country's development of advanced centrifuge models.
Britain, France and Germany say they’ve been “left with no choice, given Iran’s actions."
The measure would restrict federal funding of any offensive military action against Iran “without congressional authorization.”
The move is Iran's latest step away from its nuclear deal with world powers since Trump withdrew from the accord over a year ago.
Iran announced it has begun using advanced centrifuges to enrich uranium.
A diplomatic conflict between Tehran and Washington has flared since the U.S. pulled out of the 2015 Iranian nuclear deal.
