But there have been crimes. Leaks from Comey, McCabe. The lying “whistleblower”, schiff’s Staff for fraud, Schiff himself for conspiring to commit fraud. There have been lots of crimes.
Not as many as popular though holds. Most of the leaks are not criminal, for example.
The "defraud the government" angle is novel, and actually what is happening is the government is defrauding the people. That's not a crime.
Ciamraella might be caught in a lie about whether or not he had contact with Congress before going to the ICIG, but IMO, that's a red herring. ICIG should have said "we have no jurisdiction over POTUS." ICIG advancing a case that is out of his jurisdiction is not a crime.
There is probably a hundred or so process crimes, perjury, false statements sort of stuff.
To me, in the grand scheme of things, the government meddled with the election, big time, and it continues to do so with impunity. False or thinly sourced claims of Russian hacking, Russian interference; wildly misleading characterization of July 25th phone call. Those falsehoods sway millions of low information voters.
But it is not a crime for the government to mislead or lie to the public. Lying is what bureaucracies do, and this fact is why the founders sought a VERY limited government.
