Rubio breaks silence on leaked Signal chat: 'Someone made a big mistake'

"This thing was set up for purposes of coordinating," Rubio told reporters from Jamaica, noting the point of the text exchange carried out on the encrypted messaging application was purely so that officials knew how to communicate with their various counterparts. 

"Obviously, someone made a mistake. Someone made a big mistake and added a journalist," Rubio said. "Nothing against journalists. But you ain't supposed to be on that thing."

"I contributed to it twice. I identified my point of contact, which is my chief of staff, and then later on, I think three hours after the White House's official announcements had been made, I congratulated the members of the team," he continued. 

Rubio said that though the information was not technically classified nor did it at "any point threaten the operation of the lives of our servicemen," the information was "not intended to be divulged" and the White House was investigating the matter. 

National security advisor Mike Waltz, who reportedly set up the text chain and accidentally added the Atlantic editor, told Fox News' Laura Ingraham that he took "full responsibility" for the "embarrassing" mishap.

Similarly, Director of National Intelligence Tulsi Gabbard on Wednesday told the House Intelligence Committee it was a "mistake" to include a reporter in a text group that included "candid and sensitive" information.

She also maintained that the texts did not include any classified information while testifying in front of senators on Tuesday. 

Waltz in a Wednesday tweet said, "No locations. No sources & methods. NO WAR PLANS. Foreign partners had already been notified that strikes were imminent."

The Atlantic maintains the texts did include "attack plans."

"1410: More F-18s LAUNCH (2nd strike package). 1415: Strike Drones on Target (THIS IS WHEN THE FIRST BOMBS WILL DEFINITELY DROP, pending earlier 'Trigger Based' targets). 1536 F-18 2nd Strike Starts - also, first sea-based Tomahawks launched," he later added. 

But Rubio, in alignment with other administration officials, pointed to the Pentagon's assessment on whether its leader released classified information and said, "They made very clear that [the texts] didn't put in danger anyone's life or the mission at the time." 

"There was no intelligence information," Rubio added.
