Donald Trump started a Twitter feud with Jimmy Fallon this week, after Jimmy recently expressed regret for his softball interview with Trump during his campaign run for president in 2016.

“I’m sorry. I don’t want to make anyone angry — I never do and I never will. It’s all in the fun of the show. I made a mistake. I’m sorry if I made anyone mad. And, looking back, I would do it differently,” Jimmy had said.

But Trump wasn’t happy about it:

.@jimmyfallon is now whimpering to 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. He called & said “monster ratings.” Be a man Jimmy!

Then, Jimmy decided to use the spotlight for something good, by donating money to RAICES, which helps provide legal assistance to immigrants at the border.

In honor of the President’s tweet I’ll be making a donation to RAICES in his name.
