Rep. Don Bacon, a Nebraska Republican and one of Congress' most outspoken supporters of Ukraine, said Russian government-linked hackers recently compromised his Signal account after posing as a close acquaintance in what appears to have been a targeted phishing operation.
Bacon said that the breach occurred roughly four to five months ago and is under investigation by both the FBI and House cybersecurity officials. He said he was not concerned that classified information had been exposed because he does not use Signal to store or share sensitive material.
