So all but one of the 5 investigations I mentioned began earlier this year, and the most effective one, with appointment of special counsel, only 12 days ago.  

And yes, a 6th - the FBI's - had been going on unannounced for about 10 months.  Now another investigation is looking into whether or not Trump tried to shut that down.   That's how things go.

And to think Kellyann Conway said, only last October: "Most honest people I know are not under FBI investigation, let alone two."

It's still early days.  Even at the faster pace of the early 1970s, it took over two years from the arrest of the Watergate burglars for Nixon to resign.  Patience.
