It made major headlines, I'm surprised you're so far out of the loop you never heard about it. The link to a Google search I provided for you makes it easy to find the EO:
I did hear about that order, but it did nothing of the sort the commenter claimed it did. It did not allow 'people' to 'cancel' other people. It asked the DOJ to investigate any violations of section 230, and asked the FCC to rework its administrative rules regarding the law. It did not suspend anything. Did not create new law. That is editorial nonsense.
If you'd heard about it, you wouldn't need someone else to find cites or links, I'm not that gullible.
> Did not create new law
Right, it had no effect, just more signalling from Trump. He sought to increase the legal responsibility of social media companies for what their users say, exposing them to lawsuits, in effect silencing and canceling users.
