Then US President Barack Obama negotiated the Joint Comprehensive Plan of Action or the JCPOA in 2015 and signed it along with the five permanent members of the UN Security Council, Germany, the EU and Iran.

Trump’s remarks represent a shift for the president, who in 2018 withdrew the United States from a nuclear deal with Iran.

U.S. President Donald Trump says he sent a letter to Iran's Ayatollah Ali Khamenei, something that was not immediately confirmed by the supreme leader.

President Trump said he sent a letter to the Iranian government seeking to negotiate a deal to prevent Tehran from acquiring a nuclear weapon. The White House did not release the letter or further describe its contents.

WASHINGTON — President Donald Trump said Friday he’s written to Iran’s supreme leader, Ayatollah Ali Khamenei, about his desire to seek a new nuclear deal. “I said I hope you’re going to negotiate, because it’s going to be a lot better for Iran,” Trump said in an interview with Fox News that aired Friday.

Ayatollah Ali Khamenei, Iran's supreme leader, said in a series of X posts Saturday he would not negotiate a nuclear deal with the U.S. due to its demands.

Ayatollah Ali Khamenei decried “bullying governments” in an apparent response to a letter the White House sent to Iran earlier in the week.
