U.S. intelligence agencies leaders will testify Tuesday morning before the Senate Intelligence Committee about global security threats. 

This hearing comes after President Donald Trump’s senior national security officials accidentally shared sensitive details about strike plans on the Houthi terrorist group in Yemen with the editor-in-chief of The Atlantic through the encrypted messaging app Signal. 

The messages between Defense Secretary Pete Hegseth, National Security Advisor Michael Waltz and Vice President JD Vance and 15 other senior officials involved discussions in the lead up to the strikes carried out on the Iran-backed Houthi terrorist group in Yemen last week and raises questions about the use of the private messaging app for conducting government business. 

The hearing is set to start at 10 a.m. EST and those testifying include Director of National Intelligence Tulsi Gabbard, CIA Director John Ratcliffe, FBI Director Kash Patel, National Security Agency Director Gen. Timothy Haugh and Defense Intelligence Agency Director Lt. Gen. Jeffrey Kruse, according to CBS News.

The hearing will likely focus on threats from Russia, China and Iran, the outlet reports. 

However, leaders of the intelligence agencies will also likely be questioned about the sharing of classified information on a messaging app.
