Senate Minority Leader Chuck Schumer, D-N.Y., and top Democrats on the national security committees, are issuing a letter to Trump asking for additional details regarding a text chain about military planning that inadvertently included The Atlantic’s top editor.

“Our committees have serious questions about this incident, and members need a full accounting to ensure it never happens again,” the senators wrote.

They expressed their “extreme alarm about the astonishingly poor judgment shown by your Cabinet and national security advisors” following the report about leaked military plans for strikes in Yemen.

“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,” the senators said. “As such, it is imperative that you address this breach with the seriousness and diligence that it demands.”

The senators said that they “expect” that Attorney General Pam Bondi will conduct an investigation “of the conduct of the government officials involved in improperly sharing or discussing such information.”

The senators are also seeking the full unredacted transcript of the text chain for the committees to review, asking whether other White House officials are using Signal or other commercial platforms to discuss classified or sensitive information, and urging relevant agencies to preserve documents and correspondences regarding the incident.

In addition to Schumer, the letter was signed by the top Democrats on the Intelligence Committee, the Judiciary Committee, the Armed Services Committee, the Foreign Relations Committee, the Homeland Security and Government Affairs Committee and the Appropriations subcommittee on defense.
