Rubio warns Twitter after it puts fact-check label on Trump tweet

The law still protects social media companies like @Twitter because they are considered forums not publishers, Rubio said. But if they have now decided to exercise an editorial role like a publisher then they should no longer be shielded from liability & treated as publishers under the law.

Twitter became a publisher long ago. Trump should, except that is an objectively disordered act, just go out on the mall and kill himself for being a gross vulgarian, thus opening up the office to Pence, who seems like a solid sort to me.
