Jimmy Fallonthinks PresidentDonald Trumpneeds to work a little harder to “Be Best.”
The generally genial late night host fired back at the president during his monologue Monday evening, afterTrump targeted Fallon on Twitter Sunday night.Trump called theSaturday Night Livealum “whimpering” after Fallon recently expressed regret about an infamously lighthearted interview with the then-presidential candidate in 2016.
“.@jimmyfallon isnow whimperingto all that he did the famous ‘hair show’ with me (where he seriously messed up my hair), & that he would have now done it differently because it is said to have ‘humanized’ me-he is taking heat,” Trump wrote on Sunday evening.
During the monologue, Fallon addressed first ladyMelania Trumpand her anti-bullying campaign — hinting, as many have done before him, that her husband might be the biggest bully of all.
Sounding somewhat dumbfounded, Fallon told the audience that “As you may have heard last night, the President of the United States went after me on Twitter. So Melania, if you’re watching, I don’t think your anti-bullying campaign is working.”

Fallon also used humor to point out how stunned he was that Trump took time out of his day to address him directly.

“When I saw that Trump insulted me on Twitter, I was gonna tweet back immediately, but I thought, ‘I have more important things to do,’ ” the host said. “Then I thought, ‘Wait—shouldn’thehave more important things to do?’ ”
The comedian then showed the audience the tweet and added “That’s real. It’s crazy. The president went after me on Twitter. It’s pretty much the only thing I have in common with NFL players.”
Prior to Monday night’s show, Fallon addressed Trump’s tweet on Twitter — announcing that “In honor of the President’s tweet I’ll be making a donation to RAICES in his name.”

Trump’s tweet to Fallon came shortly after the late night host spoke out about his much-criticized 2016 segment with Trump.
“I did not do it to normalize him or to say I believe in his political beliefs or any of that stuff,”The Tonight Showhost, 41, said during an episode ofThe Hollywood Reporter’s“Awards Chatter” podcast.
“I saw other comedians from other shows making fun of me on Twitter and I go, ‘Okay, now I’m just gonna get off,’ ” he continued, before pointing out his show centers aroundlighthearted and entertaining interviews— not hard-hitting political content.
