Close to nothing happened after Snowden leaks. The republican party has been able to convince pretty much everybody that the Mueller report was a hoax, a report that very explicitly found collusion between Russia and US operatives close to Trump, so bad that his own guys went to prison. The 2nd trump admin destroyed the cyber monitoring apparatus and might have let Russian hackers access citizens data.
I don’t think there is anything to be expected from the US at this point.
