Today, Virginia U.S. Sen. Mark R. Warner, chair of the Senate Select Committee on Intelligence, issued the following statement following reports of a breach of Microsoft email accounts at over two-dozen organizations, including government agencies, by China-based hackers:

“The Senate Intelligence Committee is closely monitoring what appears to be a significant cybersecurity breach by Chinese intelligence. It’s clear that the PRC is steadily improving its cyber collection capabilities directed against the U.S. and our allies. Close coordination between the U.S. government and the private sector will be critical to countering this threat.”
