Here are some Russian sources. http://www.prospektmag.com/2017/04/7-great-russian-podcasts-you-should-listen-to-from-music-to-politics/
The first one , Arzamas, offers podcasts with transcript. http://arzamas.academy/
When I get through the other languages I am learning, there is no shortage of great Russian content.
Is there something like this for Polish?
Here are a few that I have found for Polish.

http://wyborcza.pl is really good, and they have a portable app, and transcripts, same is true for Newsweek in Polish.
