Interesting that these news outlets don't want to disclose whether or not political ad buyers are foreign or not. Two of the most vocal anti-POTUS newspapers are filing a lawsuit to stop it. You would think with all that talk about 'muh Russia' they'd be eager to get the facts out…
Their argument is that it would be too much hassle. Really? Just have the buyers fill out an online form and store the info in a database.
They're trying to hide something.
