That’s a really weak point in what should be a strong area for Conservatives today. Limitations to the First Amendment exist, and “yelling fire in a crowded room” is a very generally understood shorthand for those limitations. I’d focus less on calling him a liar over this and more on pushing back against the government doing censorship personally.
Walz said he doesn't run Facebook implying that Biden/Kamala had no impact in that decision.
Why did he lie so blatantly?
