US intelligence sharing could be impacted by a stunning security breach that saw a journalist inadvertently added to a chat group of top Trump officials discussing military plans, a Democratic senator warned Tuesday.
The United States and allies around the world share intelligence that helps keep Americans safe, Mark Warner said at a Senate Intelligence Committee hearing.
But as Donald Trump's administration insults allies including Canada and European nations, and moves closer to traditional adversaries such as Russia, the security breach could further erode trust, the lawmaker warned.
"The intelligence we gather to keep Americans safe depends on a lot of allies around the world who have access to sources we don't have. That sharing of information saves lives, and it's not hypothetical," said Warner, the top Democrat on the panel.
"However, these relationships are not built in stone. They're not dictated by law. Things like the Five Eyes are based on trust," he said, referring to an intelligence-sharing alliance between the United States, Canada, the United Kingdom, Australia and New Zealand.
