What's different about the Charlie Kirk firings

Companies are reacting to pressure from Republican officials and right-wing activists and quickly firing anyone who attempts to justify or minimize the killing of Charlie Kirk — or even criticize the slain conservative activist.

Why it matters: These firings could be legal, lawyers say, but they demonstrate fast-changing norms around free speech that many find troubling.

They also signify an increased vigilance among employers when it comes to workers' social media posts.

Where it stands: Dozens of such terminations have been publicly reported at media companies, airlines, sports teams and federal agencies.
