According to The Hill, Trump called Barr "a man of unbelievable credibility".

[lapucelle]

Unbelievable
unable to be believed; not likely to be true

Credibility
the quality of being trusted and believed in

[Faux pas]

1. Oxymoron

2. PARSE, Donald. PARSE! nt

3. What a MORAN.

4. For once I agree with Trump. Barr's credibility IS unbelievable. Absolutely.

5. I call this an oxyf'ingmoron.

6. Ugh, I think I'm gonna...

7. Trump is...

Trump is a monoxymoron. He doesn't need the usual two words to qualify for it.

It's a new thing I may have just made up, or not.

8. NOW, YOU KNOW HE'S A CROOK

Think about all the people trump has complemented in this manor, think about it---THEY ARE ALL CROOKS AND LIERS WHO WERE LOYAL TO TRUMP.

But in trump's mind, this is only in reference to how barr treats trump. Anyone who serves trump as flynn and barr has, will get that kind of praise---DOESN'T MEAN IT'S TRUE--ESPECIALLY IN THE WORLD WE ALL LIVE IN. Flynn is a lying crook who was fiercly loyal to trump and would do anything for trump, trump was desperate to get him out of jail (out of respect for his loyalty), barr serviced this need. Barr was hired to be trump's personal AG. WE REALLY NEED TO ENSURE THIS IDIOT IS VOTED AND REMOVED FROM OFFICE!!!

9. ...ayah man of believable incredibility... eom

[Vogon_Glory]

10. To which I can only ironically reply:

Unbelievable. Definitely unbelievable credibility.

I don’t believe that the man is credible.

11. Here's what I've learned about President Trump

You take half of what he says, than half that, than half even that one more time, and maybe you can believe half of that.

Trump says Barr is credible = Barr is anything but.

Rolling on the floor laughing with you lapucelle.

12. Trump and his poor grammar again

That's "Lack of credibility," there, Donald.

Fixed it for you. Go take the rest of the afternoon with some covfefe in Nambia.

13. Slip of the tongue. He meant "unbelievable criminality."

Like attracts like, after all...
