Star Wars actor Mark Hamill took to social media to mock President Donald Trump after the White House shared a post inspired by the iconic franchise which included one crucial mistake.

The White House shared a meme and video that allied Donald Trump with the Empire — the villains of the Star Wars film franchise.

What are people saying about it? Let’s start with the reaction post released by none other than Luke Skywalker himself, Mark Hamill (who visited the White House last year for Star Wars Day). Hamill was as witty as ever, writing that Trump was “full of SITH” for the post.
