WASHINGTON (WCBD) -- U.S. Sen. Lindsey Graham reaffirmed his support Wednesday for President Donald Trump’s national security team after a journalist revealed he was accidentally added to a group message with high-level officials about planned military strikes in Yemen. “President Trump and h is team admitted that having a journalist in the group text was wrong, will be reviewed and falls in the category of ‘lessons learned’ so that it doesn’t happen again,” Graham said in a March 26 statement. Jeffrey Goldberg, the editor in chief of The Atlantic, wrote Tuesday that “precise information about weapons packages, targets, and timing” regarding a March 15 airstrike on Houthi targets was shared on the thread before it happened. Goldberg said he was invited to the chat on Signal, an encrypted messaging app, by a user identified as National Security Advisor Mike Waltz.

Despite repeated assertions from Hegseth and others that no classified information was discussed, Graham acknowledged Wednesday that “very sensitive information” was disclosed on the thread. “Recent revelations about the content of the texts – while not discussing war plans per se – do in fact detail very sensitive information about a planned and ongoing military operation,” he said. The revelation sent shockwaves through Washington, with Democratic leaders calling for an immediate investigation into the matter. “Let us be clear, if any American military servicemember, intelligence official, or law enforcement officer committed such an egregious breach of operational security and endangered the lives of their comrades downrange, they would be investigated and likely prosecuted,” Schumer and the other senior Democrats wrote in a letter to Trump, according to reporting from the Hill. The National Security Council said in a statement that it was looking into how a journalist’s number got added to the chain. Some Republicans also signaled the need for a probe into the blunder but stopped short of calling for the removal of any administration officials involved.   Graham said he believes those participating in the chat were “under the impression” that the app was a secure form of communication, echoing testimony given by Ratcliffe during a Senate hearing Tuesday.   “When I was confirmed as CIA director, Signal was loaded onto my computer at the CIA as it is for most CIA officers,” Ratcliffe told lawmakers. “One of the things that I was briefed on very early, senator, was by the CIA records management folks about the use of Signal as a permissible work use.” Graham, a U.S. Air Force veteran, emphasized Wednesday that he stands by the administration, focusing on what he called the “highly successful” mission. “The Trump Administration’s decision to strike Houthi military infrastructure that was used to attack American naval vessels and international shipping was the correct response and highly successful,” he said. “The President’s national security team had already appropriately advised regional allies before the attack.” ...read more read less
