evidence: Vivek Ramaswamy says he's running an "America first" campaign, urges Iowans to caucus for him to "save Trump" [...] Ramaswamy has also increasingly leaned into conspiracy theories that resonate with a fringe element of the Republican Party as the race continues. He has suggested the Jan. 6, 2021, riot was an "inside job" and raised questions about the 9/11 attacks. "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," Ramaswamy told The Atlantic, suggesting federal agents may have been on the plane during the 9/11 attacks.
