"The problem is that the deal was made on a completely false pretense. Iran lied on the front end, they were dishonest actors and so the deal that was made was made on things that were not accurate," Sanders said at a White House press briefing. "We have a big problem with that. Particularly the fact that Iran's nuclear capabilities were far more advanced and far further along than they ever indicated."
The spokesperson was responding to a reporter's question about a typo in a statement on Iran that the White House issued on Monday. The White House initially issued a statement that said, "Iran has a robust, clandestine nuclear weapons program," but later corrected it to read, "Iran had a robust, clandestine nuclear weapons program."
She warned that once the deal expires, Iran would be able to make a nuclear weapon much quicker than previously believed.
On July 14, 2015, the European Union and the P5+1 group of countries — Russia, China, France, the United Kingdom, the United States and Germany — signed the Joint Comprehensive Plan of Action (JCPOA) — also known as the Nuclear Deal — with Tehran. The accord stipulated a gradual lifting of sanctions against Iran in exchange for Tehran curbing its nuclear program.
The International Atomic Energy Association has verified that Iran is upholding its commitments under the accord.
