Senate Minority Leader Chuck Schumer and other top Democratic senators sent a letter Wednesday to President Donald Trump and senior administration officials demanding accountability and answers on the Signal group chat used to discuss sensitive information surrounding US military strikes in Yemen earlier this month.

“We write to you with extreme alarm about the astonishingly poor judgment shown by your Cabinet and national security advisors,” wrote the senators.

“You have long advocated for accountability and transparency in the government, particularly as it relates to the handling of classified information, national security, and the safety of American servicemembers. As such, it is imperative that you address this breach with the seriousness and diligence that it demands,” the letter says.

The senators also insisted that Attorney General Pam Bondi “conduct a thorough and impartial investigation” into the chain, “given that willful or negligent disclosure of classified or sensitive national security information may constitute a criminal violation of the Espionage Act or other laws.”

Sens. Dick Durbin, Jack Reed, Jeanne Shaheen, Mark Warner, Chris Coons and Gary Peters also signed the letter. They are the senior Democrats on the Senate Judiciary Committee, Armed Services Committee, Foreign Relations Committee, Intelligence Committee, Appropriations Subcommittee on Defense, and the Homeland Security and Governmental Affairs Committee, respectively.

The senators also sent the letter to Secretary of Defense Pete Hegseth, CIA Director John Ratcliffe, Secretary of State Marco Rubio, Attorney General Pam Bondi and Director of National Intelligence Tulsi Gabbard.
