evidence: NEW YORK — While visiting the Sept. 11. memorial Monday in Lower Manhattan, Republican presidential candidate Vivek Ramaswamy said he stands by the comments he had made regarding the terrorist attacks in a recent interview. [...] The 38-year-old entrepreneur had come under fire for comments he made about the attacks during an interview with The Atlantic published last month implying that "federal agents" were on the planes during the attacks. "I think it is legitimate to say how many police, how many federal agents, were on the planes that hit the Twin Towers," Ramaswamy told reporter John Hendrickson. "Maybe the answer is zero. It probably is zero for all I know, right? I have no reason to think it was anything other than zero. But if we’re doing a comprehensive assessment of what happened on 9/11, we have a 9/11 commission, absolutely that should be an answer the public knows the answer to."
