The USMC has a long memory, and they are not stupid, like so many of his so-called “supporters”.
The UCMJ has a very specific judgment about a sentry – or commander – who lets the enemy infiltrate and kill members of his unit.
So does the Constitution.
Now then, will Republicans honor the UCMJ or the Constitution? Or go through their song-and-dance, smoke-and-mirrors routine? Maybe launch another Benghazi! style “investigation”?
