In times past, Trump would be on his way to impeachment.

2. Nixon's near-impeachment was more than two years after the Watergate burglary.

It took a long time to unravel all the complexities of "Watergate," which was far more than a simple burglary but actually a whole collection of felonies that were interconnected by the various WH personnel, GOP operatives and others. There was money-laundering, the illegal use of campaign donations to finance political sabotage, obstruction of justice by a lot of people besides Nixon, and lots of perjury. Watergate wasn't just a coverup of a burglary; it was an enormously complex coverup of multiple coverups.

What's going on now will probably turn out to be at least as complicated because of the involvement of the Russians. And it will take awhile to piece it all together. Patience.
