President Donald Trump informed France's Emmanuel Macron in a phone call this morning that he will pull the U.S. out the nuclear deal it signed onto three years ago after intense negotiations with Tehran. 

The New York Times reports that a person briefed on the conversation said Trump plans to reinstate all of the sanctions the U.S. waived in conjunction with the nuclear deal. Trump also plans to impose additional sanctions on Tehran, the Times' source said. 

Macron's office told Reuters that the Times' report was incorrect. However, European officials told the wire service that they do expect Trump to announce today that he's exiting the accord. U.S. officials told AP and AFP the same thing.

Trump's anticipated action had U.S. allies on edge. A senior British diplomat told DailyMail.com the U.K. is 'deeply pessimistic' ahead of public Trump's announcement today.
