During one pause in West's comments, Mr Trump said: "I tell you what that was pretty impressive".
"Well if he doesn't then he gets overruled by me, because I make the decisions, he doesn't", Trump said.
Talking loudly and rapidly on everything from Trump's protectionist trade polices to replacing Air Force One with a hydrogen plane, black gun crime, being married to Kim Kardashian and "infinite amounts of universe", Kanye left the normally loquacious president almost speechless.
In December 2016, West was one of the many faces to appear at Trump Tower in New York City for an audience with the president-elect.
"It was something about when I put this hat on, it made me feel like Superman", West said.
Mr. West said his intention is "to release the love throughout the country".
West has been publicly supportive of Trump since the president was elected, tweeting a photo of himself sporting a "Make America Great Again" this April and lauding Trump during the closing moments of a "Saturday Night Live" appearance in September. "A welfare mentality", he said before expressing the belief that black people "get caught up in the idea of racism".
West spoke to reporters for almost 10 minutes in the Oval Office.
West replied: "It was from the soul".
"My issue with Kanye West is quite simple - it's that anti-intellectualism simply isn't cool", said commentator Bakari Sellers.
West asked Trump to pardon Larry Hoover, the alleged founder of a notorious Chicago street gang who's serving six life sentences in a federal supermax prison in Colorado.
Looking at Trump, West added: "You made a Superman cape for me". Supporters of West's music have described him as a political sellout.
West's wife, Kim Kardashian West, has been to the White House twice in recent months to discuss criminal justice reform and the clemency process.
"I love this guy", West declared in the Oval Office.
"It hurts us because we need to focus on who were are today", he said.
