The Latest: Senators Press Administration On Iran deal

Iran's President Hassan Rouhani listens at a news conference during his visit for the United Nations General Assembly, Wednesday Sept. 20, 2017, in New York. President Donald Trump said he has made a decision on whether to walk away from the landmark 2015 nuclear deal with Iran but refused to say what it is, setting the stage for a particularly contentious meeting of the parties to the agreement.

NEW YORK (AP) — The Latest on the United States and Iran (all times local): 3 p.m. A group of Democratic senators is pressing the Trump administration to comply with a law that requires the administration to tell Congress of potential breaches by Iran of the landmark nuclear deal.

The senators say the executive branch must share with Congress any Iranian violations within 10 days of receiving that information. The lawmakers say they've received no such notifications so far. In fact, the lawmakers say in a letter to Secretary of State Rex Tillerson and other national security officials that they've been told the opposite. They say Gen. Paul Selva, the vice chairman of the Joint Chiefs of Staff, testified in July that Iran is abiding by its commitments.

The letter is being sent amid signs that President Donald Trump may walk away from the nuclear accord.

11 a.m.

President Donald Trump says he's reached a decision on whether to pull out of the Iran nuclear deal — but he won't say what it is.

Trump was asked several times on Wednesday whether he'd reached a decision. His answer: "I've decided."

And he answered, "I'll let you know," when he was asked for details.

The president made the comments during a meeting in New York with Palestinian Authority President Mahmoud Abbas.

Trump — in his U.N. speech on Tuesday — called the 2015 nuclear deal an "embarrassment" to the United States.

The president has until Oct. 15 to certify that Iran is complying with the deal. Under the agreement, Iran has halted nuclear development in exchange for the lifting of economic sanctions.

The United States and Iran are planning for their highest-level interaction of Donald Trump's presidency. It'll come just a day after Trump delivered a blistering attack on Iran and the landmark 2015 nuclear deal — and sent strong signals he could walk away from that accord.

Secretary of State Rex Tillerson and Iranian Foreign Minister Mohammad Javad Zarif are expected to attend a European Union-hosted meeting about the agreement at the United Nations later Wednesday.

The closed-door gathering is expected to be contentious, and its lead-up has been marked by Washington and Tehran trading increasingly harsh barbs.
