Trump said Tuesday that the deal was "a great embarrassment" to all American citizens, and has only helped Iran develop its nuclear arsenal.  

Trump is set to decide by May 12 whether to pull out of the Iran deal. Trump has all but decided to withdraw but exactly how he will do so remains unclear, two White House officials said.

U.S. President Donald Trump on Friday will extend waivers on Iran nuclear sanctions, keeping alive the landmark 2015 deal for at least another several months despite his past vows to scuttle the deal, officials said.
