Because of the 5th Amendment. You can bet your ass that the DoJ will take your words and use them to charge you of a crime if you admit to it in front of Congress.
The real question is why was a man who was given a FULL PARDON by Sleepy Joe Biden allowed to plead the 5th? If you have a pardon you're already free from prosecution, so legally you have NO 5th Amendment right to stand on.
Let's take your bullshit comment apart piece by piece, shall we?
1. Trump is evicting ILLEGAL IMMIGRANTS and no one else. He's actually favor of LGBT rights, by the way, and if you'd pull your head out of your ass and read some real news instead of that shit on CNN and MSNBC you'd know that.
2. Trump has full authority under the War Powers Act to do what he's doing with Iran.
3. The network shut down Colbert, not Trump. Again, stop watching CNN.
4. Trump hasn't brainwashed anybody. We follow and support him because we believe in what he's doing. If anyone is brainwashed it's you, and your comment is proof of that. But never mind that you and your fellow brainwashed lemmings followed Biden, Harris, and Fauci for 4 years, believing everything they said and denying all of the facts and evidence that proved otherwise. Noooooo, let's not talk about that.
As for your so-called "bonus round"...
1. Where else are you going to find oil except underground? So you don't want American to be energy independent? Moron.
2. Trump can't elect anyone. And speaking of idiots, once again your own comment proves YOU to be the idiot.
You're gonna hate it when Vance gets elected in 2028.
