The first part massively reinforced by the second. Maybe "because" is a stretch. Obama not Trump was the president when the Snowden leaks happened. Bush was president when it was going on. There was a lot of real evidence of crime there that went un-prosecuted. Crimes kept going. Extra-judicial droning of US citizens seems like a bigger deal that burglary of a psychiatrist office.
Something else to consider is that Watergate is orders of magnitude more of a scandal and has the mindshare to match compared to COINTELPRO.
Should that have been? Should it be now?
