evidence: Vivek Ramaswamy asked if federal agents were on hijacked 9/11 planes Republican presidential candidate Vivek Ramaswamy went into cleanup mode Tuesday, after newly released audio revealed he openly questioned whether federal agents were aboard the hijacked planes on 9/11. A profile by Atlantic staff writer John Hendrickson published Monday quoted Ramaswamy as saying: "I think it is legitimate to say how many police, how many federal agents, were on the planes that hit the Twin Towers. 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.
