“John Kerry can’t get over the fact that he had his chance and blew it!” Trump tweeted Tuesday. “Stay away from negotiations John, you are hurting your country!”
Trump has declared that he would pull the US out of the nuclear deal, known as the Joint Comprehensive Plan of Action (JCPOA), which lifted nuclear-related sanctions on Tehran in exchange for curbs on its nuclear program.
The US has announced to decide on the issue later today as European allies of the United States, particularly the UK, are reportedly trying to convince the president to stay in the deal backed by five other world powers.
On Monday, Trump criticized Kerry over his efforts to shield the agreement and suggested the former secretary of state could be committing a crime.
“The United States does not need John Kerry’s possibly illegal Shadow Diplomacy on the very badly negotiated Iran Deal” Trump tweeted. “He was the one that created this MESS in the first place!”
During a speech to the National Rifle Association on Friday, Trump attacked Kerry for his initial role in negotiating the Iran deal, which Trump called "horrible."
"And we have the former administration as represented by John Kerry, not the best negotiator we've ever seen," Trump said. "He never walked away from the table, except to be in that bicycle race where he fell and broke his leg."
Russia and China, as the other signatories to the JCPOA, have warned against efforts to scrap the landmark accord and pledged to continue to honor their commitments under the deal.
Trump has repeatedly argued that the accord was poorly negotiated.
