While Ramaswamy's campaign did not immediately respond to a request for comment, the presidential candidate commented "this was ironic" on a post on X that also reported that a protester hit his car before speeding away.
He reposted images of two cars - one which appeared to have damage to the back fender. It is unclear whether the image is of Ramaswamy's car.
"I believe in free speech, especially for those who disagree with me. Violence is never the answer," Ramaswamy said in a post on X.
"We will always hold ourselves to a higher standard than the other side."
Ramaswamy has stoked grassroots chatter as a potential alternative to former President Donald Trump, whom he fervently supports.
According to Reuters/Ipsos polling conducted from Sept. 8-14, his support stood at 13% among Republicans, a close third to DeSantis, who is fighting to preserve his status as the second-place candidate.
Trump is the frontrunner in the Republican party's race for the presidential nomination.
