Castle Clean
I think I know what "Castle Clean" could mean.
On 01/15/202020, it became known that Russia is changing its government team.
Medvedev resigned unexpectedly with his team.
Where is the headquarters of the Russian government?
The Kremlin!
What is a Kremlin?
An inner-city fortification, a castle!
Does it matter? Medvedev is a Jew.
