Donda died in 2007 of heart disease while suffering “multiple post-operative factors” following a plastic surgery operation.

On Sunday, West posted a photo of himself on Twitter wearing a pro-Donald Trump “Make American Great Again,” writing: “This represents good and America becoming whole again. We will no longer outsource to other countries. We build factories here in America and create jobs. We will provide jobs for all who are free from prisons as we abolish the 13th amendment. Message sent with love.”

The unrehearsed monologue was met with some boos from the audience and made the show’s stars “uncomfortable,” a source previously told PEOPLE.

“He’s up in the middle of the night texting, calling, messaging everyone and he doesn’t make any sense,” continues the insider. “He’s rambling. His ideas aren’t always completely bad, but then he can’t communicate them and it gets confused in his own mind. He’s such a confused guy.”

According to the insider, the entertainer believes he is fighting “dark spiritual forces” that are “evil.”

“Of course he’s ‘good,'” explains the insider. “‘Evil’ can change depending on what we’re talking about. If he has writer’s block, it’s evil. If someone disagrees with him, they’re evil. We’re always telling him, ‘No, that’s not evil. That’s just life.'”
