President Trump says he will announce Tuesday 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.

President Trump has called it the "one of the worst deals" he has ever seen — but for now, he is keeping the U.S. in the nuclear deal with Iran.

The president decided Friday to continue waiving — that is, easing — some economic sanctions against Iran. That is part of the U.S. commitment in the 2015 nuclear deal known as the Joint Comprehensive Plan of Action.

Under the deal, Iran allows strict limits on its nuclear program in return for easing of economic sanctions.

In 2015, world powers agreed to give Iran relief from some economic sanctions in return for inspections and limits on its nuclear program. Since the nuclear deal — formally known as the Joint Comprehensive Plan of Action — took effect in January 2016, Iran has allowed inspections and is seeing some economic payoff.
