Fiorina essentially watched a heavily spliced Youtube video of the first Star Wars trilogy in which, through clever cuts and dubbing, it is revealed that Obi Wan Kenobi is Han Solo's father. Fiorina then described to the American people, in lurid detail, how you can watch Solo murder Obi Wan in cold blood with a blaster as Obi Wan intones "if you strike me down, I shall become more powerful than you can possibly imagine."
We all know she's referring to Empire Strikes Back---and has confused events a bit with the first and third movie, who can keep them straight---but her conclusion is, of course, invalid. First, in the edited video, the murder actually takes place off-camera and is just described by an Imperial Stormtrooper who had infiltrated the rebel base. Second, the video does not portray the events that actually occurred in the trilogy (a minor point, to be fair). However, to your point, her comments (although inaccurate) clearly referenced and corresponded to an existing video released by starwarstruth184, of which fully 80% was sourced from the trilogy, along with 10% from Spaceballs and 5% from Kubrick's 2001, which similarly also takes place in space.
After being fact-checked and declared to be lying about the plot of Star Wars by several organizations--with the exception of CNN, who fell asleep during their Star Wars marathon and thus rated her statements as "plausible" out of 10--Fiorina doubled down, declaring events were exactly as the way she described them down to the slow-motion blood spatter on R2D2's carapace, that detractors obviously had not even watched the movies, and that they were "Lucas liberals" and part of the "Industrial-Light-and-Magic complex".
Pressed further, Fiorina angrily responded that "HAL shot first".
