The main stories usually involve more research, so I imagine they're prepared well in advance. But it'll probably get covered in one of the shorter segments preceding the main story that pad out the running time (those don't make it on the official YouTube but I think they're more topical).
They do make it on the official YouTube if you are not in the US.
They publish the full episodes on YouTube for people that can't have access to them legally.
Huh, didn't realize that! They've started publishing their back catalog for the US recently (first three seasons are up on YouTube), but yeah, now that I check SocialBlade I can see that the full episodes get uploaded alongside the main segments (e.g. this most recent episode). Seems like they're blocked in the Anglosphere + India, most of Western Europe + Greenland (except France), all of Africa, the Arabian Peninsula, Afghanistan, China, and Venezuela. So if you're in Central/South America, Eastern Europe, most of the Middle East, or Asia (besides those noted exceptions), you're in the clear!
