German Chancellor Angela Merkel said on Friday that she will stay in close touch with U.S. President Donald Trump on the 2015 nuclear deal.

Merkel was in Washington for a brief “working visit” with Trump, according to BBC.

Trump has said he will make a decision on whether to leave the deal by May 12.

Except the U.S. all other parties to the nuclear deal, including the European Union, France, Germany, Britain, Russia and China, have reiterated their full support for the international nuclear agreement.
