Bennie Thompson: “In an age of on-line radicalization, violent extremism commands the largest microphone it has ever known.”

It should go without saying that administration officials should not be using Signal for discussing intelligence matters reserved for the situation room — not to mention doing so incompetently by including members of the public.

This unlawful policy is a smokescreen to deny Member visits to ICE offices across the country, which are holding migrants – and sometimes even U.S. citizens – for days at a time.

At a time when DHS is rightly warning about an elevated threat environment from terrorists and cartels, we should be focused on plugging security gaps rather than senselessly creating new ones.

If ICE has nothing to hide, DHS must make its facilities available.
