"Frankly, that deal is an embarrassment to the United States, and I don't think you've heard the last of it - believe me", he declared.
"The Iran deal was one of the worst and most one-sided transactions the United States has ever entered into", Trumpsaid.
Trump hinted in his speech on Tuesday that he may not recertify the agreement, negotiated by his predecessor, Barack Obama.

Emmanuel Macron spoke Wednesday evening in the sidelines of the general Assembly of the united nations.
KELEMEN: Well, the EU's foreign policy chief, Federica Mogherini, who chaired it came out, calling it frank, which is kind of diplo-speak for tough. These include its antipathy to Israel, support for terrorism and Syrian President Bashar Assad, ballistic missile testing and its nuclear program. We all agreed that all parties are fulfilling their commitments. "That applies in particular to Iran's nuclear agreement", Gabriel told the UN General Assembly on Thursday, Xinhua news agency reported. "It was a very, very matter of fact exchange about how we see this agreement very differently".
"So I think the Iranians are already thinking one step ahead as I think they are beginning to feel that it's likely that Trump will pull out".
Russia's top diplomat, Foreign Minister Sergey Lavrov, in his address, called the Iran deal one of the "more important factors of regional and worldwide security" today.

Iranian President Hassan Rouhani said Wednesday that his country will not be the first to violate the agreement, but will respond "decisively and resolutely" to its violation by any party. Read on for a look at what the deal is, and what Trump has said he would do about it.
"This agreement is not something someone can touch", Rouhani told reporters at a news conference. This is a building from the frame of which, if you take off a single brick, the entire building will collapse.
Trump often calls the Iranians the rogue regime.
They tell NBC News that he's leaning toward decertifying the deal before the next compliance deadline on October 15. Haley was also in the Iran meeting on Wednesday, though in the past US ambassador did not attend such meetings.
