President Trump is expected to announce Tuesday he will not continue sanctions relief for Iran, a major step toward ending the 2015 nuclear pact he has long blasted as the “worst deal ever.”

Specifics about the steps Trump is expected to take are still unknown, such as how long it might take to reimpose sanctions on Iran that were lifted under the deal. 
 
Trump will reveal his decision to the public at 2 p.m. in the Diplomatic Room of the White House. 
 
Regional experts and foreign leaders alike expect Trump to move toward pulling out of the deal, which was negotiated by President Obama’s administration.
