Don Cheadle, acclaimed actor and true-blue mensch.

The man behind Marvel's War Machine mask brought his politics to the Saturday Night Live stage on Feb. 16. He used fashion to make a statement, at one point introducing Gary Clark, Jr., the night's musical guest, while wearing a simple t-shirt adorned with the words "PROTECT TRANS KIDS."

It was a well-received fashion choice, to say the least.

Sunday morning Twitter is flooded with support for Cheadle under the #ProtectTransKids hashtag.

The power of this moment is beyond articulate words. Applause to @DonCheadle. Your heart is true. #ProtectTransKids https://t.co/oOJvUjXmqU — Larry Flick (@LarryFlick) February 17, 2019

Trans kids have a (super)hero in their corner now. Thank you @DonCheadle for using your platform to make such an important statement. #ProtectTransKids #WontBeErased — National Center for Transgender Equality (@TransEquality) February 17, 2019

It wasn't Cheadle's only fashion statement of the night, however. Later on, during the full cast outro at the end of the show, the guest host stepped onto the stage wearing a red and white jersey adorned with the letters "CCCP," the Russian abbreviation for the former Soviet Union.

The puzzling show of pro-Russia nationalism made sense only after Cheadle turned around. The number on the back of the jersey? 45. The name? Trump.

The crowd went wild.

Last night on #SNL Don Cheadle wore a #ProtectTransKids shirt and a Russian Trump jersey.



He continues to show that he is truly the real deal, and simply a great person. Great way to use your platform, @DonCheadle. pic.twitter.com/cU0vn3uDf3 — Frederick Joseph (@FredTJoseph) February 17, 2019

Good on Cheadle for his efforts to make the name "Don" great again. His fashion statements didn't land with everyone though. Another notable Don took issue with the latest Saturday Night Live's creative choices.

Nothing funny about tired Saturday Night Live on Fake News NBC! Question is, how do the Networks get away with these total Republican hit jobs without retribution? Likewise for many other shows? Very unfair and should be looked into. This is the real Collusion! — Donald J. Trump (@realDonaldTrump) February 17, 2019

It's not clear if it was Cheadle that got to him or Alec Baldwin's cold open, or both. Not that it matters. Trump's having a bad Sunday either way. That's a win no matter what.
