Please answer this: Extract the answer to the question from the following context. Question: Aside from Kanye West, who else was critical of Bush's response to Katrina? Context: Bush stated in an interview that the comment was "one of the most disgusting moments" of his presidency. In November 2010, in a taped interview with Matt Lauer for the Today show, West expressed regret for his criticism of Bush. "I would tell George Bush in my moment of frustration, I didn't have the grounds to call him a racist", he told Lauer. "I believe that in a situation of high emotion like that we as human beings don't always choose the right words." The following day, Bush reacted to the apology in a live interview with Lauer saying he appreciated the rapper's remorse. "I'm not a hater", Bush said. "I don't hate Kanye West. I was talking about an environment in which people were willing to say things that hurt. Nobody wants to be called a racist if in your heart you believe in equality of races." Reactions were mixed, but some felt that West had no need to apologize. "It was not the particulars of your words that mattered, it was the essence of a feeling of the insensitivity towards our communities that many of us have felt for far too long", argued Def Jam co-founder Russell Simmons. Bush himself was receptive to the apology, saying, "I appreciate that. It wasn't just Kanye West who was talking like that during Katrina, I cited him as an example, I cited others as an example as well. You know, I appreciate that."
