If you are outside of the US, or have a VPN that *cough* allows you to travel outside the US, the full episode posts to his YouTube on Sunday evenings. If you are inside the US, the "main story" posts on Thursday, 5 days later.
John Oliver did a deep dive on Project 2025 tonight that should be required viewing. Frightening shit. Hasn't been posted on their YT channel yet, but it's a must watch. Great reporting.
I'm traveling right now and was so surprised to see his full episodes available. I assumed they always only posted the main story and never bothered to check.
I didn't have enough room to note that it's really if you are inside any country where it streams officially, then you only get the main story on YouTube days later. If you're in a country where they don't have a streaming deal, they make the full episode freely available on YouTube.
