I haven't seen any reliable reports about Beto O'Rourke hitting children with a car. It's important to base our beliefs on facts, and until there is solid proof, we should consider this story as untrue.
There is no evidence to suggest that such a horrible event involving Beto O'Rourke running over children has occurred. In the world of politics, false stories are sometimes spread to smear a candidate's reputation. We should be cautious about believing such unsubstantiated claims.
Most likely it's a fabricated story with no real origin. It could be started by someone with a political agenda against Beto O'Rourke to spread false information and damage his public image.
Perhaps an interesting aspect is how his children interact with their peers in the context of his public life. Do they face any unique challenges or opportunities because of their father's status? This could be a fascinating part of the story.
