(CNN) – Long before rapper Kanye West ruined musician Taylor Swift's night at the 2009 MTV Music Awards, he single-handedly caused one of the lowest points in George W. Bush's presidency.
That's according to the former president in an interview with NBC's Matt Lauer, during which he said West's unexpected outburst during a 2005 Hurricane Katrina telethon amounted to "one of the most disgusting moments in my presidency."
"That [means] 'he's a racist,' " Bush tells Lauer in an upcoming interview, according to the Today Show Web site "And I didn't appreciate it then. I don't appreciate it now. I resent it, it's not true."
Pressed if Bush meant to say that the West moment was more difficult for him to deal with than witnessing the devastating destruction caused by Hurricane Katrina, Bush said no.
"I also make it clear that the misery in Louisiana affected me deeply as well," Bush said.
"There's a lot of tough moments in the book. And it was a disgusting moment, pure and simple."
During the widely-viewed 2005 Concert for Hurricane Relief, West said in an unscripted moment said that "George Bush doesn't care about black people." Telethon producers quickly cut West's microphone before he could say more.
