Fallon's playful, softball interview, which ended with his toughest question - whether Trump would let him mess up the candidate's hair - has inspired a lot of heated criticism among viewers and members of the media.
Huffington Post writer Maxwell Strachan called the interview "an extended on-air puff piece" and dinged Fallon for playing nice with a controversial figure running for the highest job in the nation. Strachan compared Fallon's Trump interview with one done by Letterman, who retired from late night.
"At their best, late-night hosts have been able to toe a difficult line between comedy and responsibility. No one did this better than David Letterman, who repeatedly exposed truth while still on the air," Strachan said.
He went on to say, "Fallon is not Letterman, and he will never will be, nor does he seem to want to be. But that doesn't mean he be let off the hook for humanizing a well-documented xenophobic, racist, and misogynistic serial liar, which is exactly what he did on Thursday."
A chorus of viewers took to social media to express their anger with Fallon:
I can't make any jokes about Jimmy Fallon. The way he showcased Trump like a lovable old grandpa was sickening.
Fallon and Trump are 2 sides of the same coin: mediocrity and evil go together.
