President Trump says he will announce Tuesday at 11 a.m. whether he is going to keep the U.S. in the Iran nuclear deal. This comes after Trump has allowed the deal to stay in place through the first 15 months of his presidency while frequently criticizing it and threatening to pull the U.S. out of it.

The 2015 deal is officially known as the Joint Comprehensive Plan of Action and was the result of complex negotiations between Iran and six world powers — the United States, France, Germany, the U.K., China and Russia. The deal lengthened the time that Iran would need for "nuclear breakout," ensuring that Iran could not rush to build a nuclear bomb undetected.
