Would be a total embarrassment!
OTOH...don't feel too badly about it; there have been a few others here who also posted that patently ridiculous thing as well.
The president may TWEET some outlandish things ( I LOVE THEM ALL! ), but I doubt that he has 1) the time 2) inclination 3) ability to write something even remotely like the stupid Op-Ed, in words and style that is the antithesis of his normal screeds.
And NO, it would NOT be an "embarrassment" for the MSM nor the lefties! It would badly tarnish Trump!
