Kanye West and President Donald Trump during a meeting in the Oval Office of the White House in Washington, D.C. on Oct. 11, 2018.

After President Trump signed the Music Modernization Act into law on Thursday (Oct. 11), Kanye West – who was present in the Oval Office – went on a lengthy monologue about everything from prison reform to mental health to the 13th Amendment.

"When I put this hat on, it made me feel like Superman," Kanye said of his contentious decision to regularly wear Trump's Make America Great Again hat. He also defended his controversial tweet about abolishing the 13th Amendment, which abolished slavery, arguing the 13th Amendment was "a trapdoor" for African Americans to end up in prison "next to the Unibomber." He said the fact that most skyscrapers don't recognize having a thirteenth floor (13 is regarded as unlucky per superstition) is an indicator that the amendment should be removed. "I think the way the universe works is perfect—we don’t have 13 floors, do we?"

In addition to bragging about his IQ and the success of his Yeezy sneakers for Adidas, West said his bipolar disorder diagnosis may have been incorrect and he may only have been suffering from "sleep deprivation" all along.

Toward the end of his lengthy monologue, Kanye said he's always trying to tell Saturday Night Live and "the liberals" that they need to support the president because "if he don't look good, we don't look good. He needs to be the freshest, the flyest."

In that vein, West showed Trump a GIF of a hydrogen-powered plane, explaining he wants to work with Apple to develop the environmentally friendly aircraft, and that Trump should replace Air Force One with a hydrogen-powered flyer.

When West finished, Trump – who had been nodding silently along throughout, only correcting West at one point when the rapper said Minnesota when he meant Wisconsin – declared, "I'll tell you what, that was pretty impressive."

Earlier in the visit, someone asked if Kanye could be president in the future. Trump replied, "Could very well be," to which Kanye added, "Only after 2024." The two also hugged during the visit.
