President Donald Trump continued his assault on John Kerry, tweeting that the former secretary of state "blew it" with Iran last time and is "hurting" his country this time.
Trump has been after Kerry since a report surfaced that Kerry met with a top Iranian official to do his part to preserve the nuclear treaty with Iran, signed when he was secretary of state to President Barack Obama.
Trump on Monday said Kerry's "shadow diplomacy" was not needed now, since he "created this mess in the first place."
Trump on Tuesday is poised to announce his decision about whether to remain or pull out of the nuke accord.
