During an interview in Harrisburg, Pennsylvania, the President pointed fingers at his predecessor for sending “plane loads” of cash in order to solidify the nuclear pact between the US and Iran.
He said: “It should have been taken care of long ago.
“I think it was one of the most incompetently drawn deals I’ve ever seen, we got nothing.
“Clinton gave them billions of dollars, gave them lots of other things and before the ink was dry on the contract they were already starting again with the missiles and with the nuclear, frankly.
“They got a path to nuclear weapons very quickly and think of this one — $1.7billion (£1.2billion) in cash — this is cash out of your pocket. You know how many airplane loads that must be?

“So this is the worst deal. We got nothing. We got nothing.”
After the Joint Comprehensive Plan of Action (JCPOA) went into effect, the Obama administration delivered $1.7billion (£1.2billion) in frozen assets to seal the deal.
When questioned on the future of the pact between Tehran and Washington, the President stated that an announcement is imminent.
He continued: “I know exactly what I’m going to do, but I can’t give it away tonight. But I’m going to be announcing it very shortly.
“The people of Iran are great people and they want freedom and they want to be sort of friendly with us. I really believe that.
“But they’re dancing in the streets and they’re singing death to America, and [John] Kerry’s out there negotiating a deal, and giving up every single point.
“So we will see what happens pretty soon. A lot of people are guessing, but maybe there’s not so much guessing.”
Tensions have flared between the US and Iran recently after the latter claimed that “all options are on the table” and that a “crushing” reaction will be delivered to the US if the country persists with labelling the Iranian army as a terrorist group.
Iran’s desire to increase global tensions came as Donald Trump is in the process of deciding whether to decertify the nuclear pact the US currently holds with Tehran.
The 2015 deal resulted in Iran agreeing to limit its nuclear program in exchange for the lifting of economic sanctions, that have proved to be an essential component in Tehran’s economic growth.
The President of Iran, Hassan Rouhani, recently stated that Mr Trump’s threats to decertify the deal will not undo the trading relationships that have already flourished.
Mr Rouhani stated: “In the nuclear negotiations and agreement we reached issues and benefits that are not reversible.
“No one can turn that back, not Mr Trump or anyone else.”
Donald Trump has until October 15 to decide if the US should remain a part of the pact.
If Donald Trump chooses to decertify the deal, Congress will have an ultimatum of 60 days to decide whether to reimpose sanctions on Tehran that were lifted under the details of the deal.
