The White House on Wednesday released a statement saying that President Donald Trump had signed the nuclear deal with Iran on Monday.
The White house did not provide any further details about what Trump said during the signing ceremony.
The deal was first announced in June.
Trump is expected to sign the deal on Friday.
The Iran deal, which includes sanctions relief for the U.S. and Iran’s nuclear program, has long been the subject of intense scrutiny and criticism.
The president’s son-in-law and senior adviser Jared Kushner and other senior administration officials were among the many who attended the signing.
White House press secretary Sarah Huckabee Sanders on Wednesday declined to comment on Trump’s signing.
“The president is focused on getting the United States out of the Middle East and confronting the threat of ISIL,” Sanders said.
Trump also met with Secretary of State Rex Tillerson and Defense Secretary Jim Mattis in the Oval Office on Wednesday.
The two officials said that Trump agreed to work with Iran to curb the flow of Iranian-made advanced centrifuges and ballistic missiles to Hezbollah, the Lebanese Shiite group with a long history of terrorism.
Trump and the leaders of Iran and Saudi Arabia met with the leaders and foreign ministers of France, Germany, Russia and the United Kingdom on Monday, but the White House did not give a time frame for the meeting.
The U.N. nuclear watchdog on Wednesday criticized Trump for signing the nuclear agreement, calling it a “dangerous step toward nuclear proliferation.”
The Nuclear Nonproliferation Treaty requires member countries to restrict the export of advanced centrifuge technology.
The NPT is also intended to ensure that Iran does not build a nuclear weapon.
