President Donald Trump of the United States wrote on Twitter, Sunday afternoon, Washington time, "These Media Posts will serve as notification to the United States Congress that should Iran strike any U.S. person or target, the United States will quickly & fully strike back, & perhaps in a disproportionate manner. Such legal notice is not required, but is given nevertheless!"
He was responding to criticism that he did not notify Democratic Congressional leaders in advance about the elimination of Iran Revolutionary Guard Corps Commander Qasem Soleimani.
