Investigate dem Dems?

[Kitsune9tails]

Some people, namely me, feel that Trump should have perhaps been vetted and investigated more thoroughly by the alphabets before taking office, in order to avoid some of the circumstances he has been accused of.

Should the alphabets be currently investigating the current crop of people of various parties that are running for President? Should any such investigation wait for the nomination? Should it not occur at all?

Sure, running for President isn't necessarily Probable Cause in and of itself, but I am under the impression that you could investigate the people on the foreign end of any of say, Andrew Yang's previous business deals, even if it is illegal to investigate the man himself?
