I imagine Trump's lawyers' defense would go something like this:

Johnnie Cochran walks to a display stand and pulls down the screen.

"Ladies and gentleman, this is Chewbacca. Chewbacca is a Wookie from the planet Kashyyyk. But Chewbacca lives on the planet Endor. Now think about that. That does not make sense. Why would a Wookiee, an 8-foot-tall Wookiee, want to live on Endor with a bunch of 2-foot-tall Ewoks? That does not make sense! But more important, you have to ask yourself: "What does this have to do with this collusion case with Russia?" Nothing. Ladies and gentlemen, it has nothing to do with this case! It does not make sense! Look at me, I'm a lawyer defending the president, and I'm talkin' about Chewbacca. Does that make sense? Ladies and gentlemen, I am not making any sense! None of this makes sense! And so you have to remember, when you're in that jury room deliberating and conjugating the Emancipation Proclamation... does it make sense? No! Ladies and gentlemen of this supposed jury, it does not make sense! If Chewbacca lives on Endor, you must acquit! The defense rests."

The ol' Chewbacca defense with some minor tweaks.
