While infidelity is technically still a crime per UCMJ for persons who have signed a UCMJ contract, my understanding is that infidelity is very rarely prosecuted

AFAIK the president is not subject to the UCMJ despite being the command and chief otherwise there are many actions by many presidents I am certain would have them in front of a military tribunal. A sitting president can not be court-martialed. As a side note I knew a few people that were caught cheating when I was in the military and their lives were turned upside down by the Chief Master Sergeant.

Clinton was impeached for perjury about infidelity, but not for perjury about not inhaling.

One of those is really hard to prove unless tested immediately afterwords. On the other hand ejaculate on a dress allows for genetic testing. All recent presidents DNA are on file.

The President is not prohibited from pardoning themself for UCMJ offenses.

Infidelity that requires people at work to lie for you is the military's problem.

Apparently exoneration by one's partner for example in an open marriage does not change whether infidelity is an offense per UCMJ.

On a standard DNA paternity test, one's parents will test positive.

Wouldn't keeping DNA on file (and other biosignatures like heartbeat at a distance) make it easy to identify actual.

That person didn't remember their wife in a deposition. And, "I thought he was pretty good at what he did."

It turns out that orders are nullifiable in cases of usurpation, but what about fraudulent use of likeness by one's own kids on bibles and beer pong sets, for example.
