Why did T-rump hand pick a bunch of liars to fill the White House ?

When T-rump promised he was going to hand-pick the 'best of the best' to fill key posts in his administration, why in the world did he choose so many liars? The latest is Don McGhan, who filled in as his personal counsel in the White House.

For more than thirty hours, McGhan sat for special counsel Mueller and his team, and explicitly said that T-rump ordered McGhan to have Mueller removed. This is in the Mueller report.

McGhan explained in detail how T-rump asked McGahn to inform then-Deputy Attorney General Rod Rosenstein that Mueller was too conflicted to serve as special counsel, just days after media reports revealed that the special counsel was looking into whether Trump obstructed justice and for the first time was personally a target of the investigation. McGhan said he threatened to quit before ever doing this, which was obstructing justice.

T-rump now says McGhan lied. Lied to the investigators. He's nothing but a liar.

Just like Bannon, Omarosa, Priebus, Tillerson, Cohen, Sessions, and the other two dozen 'best of the best' he surrounded himself with over the past three years. All a bunch of liars!

So why did T-rump hand-pick a bunch of liars to fill the White House?
