President Trump on Monday criticized former Secretary of State John Kerry for his role in creating the “very badly negotiated” Iran nuclear deal and engaging in “possibly illegal shadow diplomacy.”

“The United States does not need John Kerry’s possibly illegal Shadow Diplomacy on the very badly negotiated Iran Deal. He was the one that created this MESS in the first place!” Trump tweeted.

The president was referencing a report from the Boston Globe that detailed how Kerry, who served as secretary of state under former President Barack Obama, has been working to preserve the Iran deal.

Kerry has reportedly met with Iranian Foreign Minister Javad Zarif and other European officials in an attempt to salvage the deal.
