I strongly urge a thorough investigation into the apparent mishandling of sensitive military communications via the Signal app. Based on the reporting, it appears that officials openly discussed classified operational details regarding a mission against Houthi rebels in Yemen within an insecure group chat. This would represent an egregious breach of protocol for safeguarding classified information. Holding leaders accountable for such reckless actions is paramount to maintaining operational security and protecting intelligence sources and methods. Disclosing details of counterterrorism operations risks jeopardizing future missions and endangering the lives of U.S. personnel and allies. It is unacceptable for cabinet members and senior advisors to treat classified information so carelessly. I implore you to use all available investigative resources and legal authorities to determine exactly what transpired and take appropriate disciplinary measures against any individuals found criminally negligent in their handling of classified materials. Failure to enforce stringent information security standards severely undermines national security. Those entrusted with our nation's secrets must face severe consequences for violating that trust. I urge aggressive prosecution to the fullest extent of the law in this matter.
