1. Source that claim.1. Trump admin did not add Signal, it was in use by the Biden admin.
2. There is another secure app that should have been used.
3. Where was your outrage when 13 Americans were killed in AFG because the Biden admin didn't allow a sniper to kill the suicide bomber?
4. No harm, no foul, lesson learned.
2.It wasn't. What's more it's not just insecure, it also deletes messages. Which is illegal.
3. Whataboutism is a fallacious argument. Something any fifth grader understands. Two wrong's don't make a right, and you will NEVER find me on this board defending security breaches no matter who makes them. You are. Not just that. Your analogy doesn't even compare security breaches. So it's a false analogy.
4. Of course there's a foul. If nothing else it shows hostile foreign nations that the Trump administration is perfectly happy discussing HIGHLY classified information on civilian and device specific mediums. Not to mention that they are very cavalier about operational security in general, as is shown by inviting a REPORTER to the deliberations. You don't think that's harmful?
