A new campaign ad for Republican Vivek Ramaswamy's Ohio governor race has sparked controversy and debate over what crosses the line in political advertising, according to a CBS News video report. The ad features the estranged mother of his Democratic opponent, Amy Acton.

The CBS News report, which includes reporting by Nancy Cordes, is headlined with the question "how low is too low" and describes the woman in the ad as Acton's estranged mother. The report's title also refers to the ad as an attack ad.

NPR reported that the ad from Ramaswamy's campaign shows Acton's mother calling her a liar. According to the NPR report, written by George Shillcock, the ad appears amid accounts by Acton of an abusive childhood. NPR's headline states that the backlash "upends" the race for governor.

The two reports describe the episode in different terms, with CBS News citing debate over what crosses the line and NPR citing backlash in the race. The published summaries of both reports do not describe the full text of the ad or any response from the Ramaswamy campaign or from Acton.

The summaries also do not identify the people or groups who have made the arguments in the debate, and they do not say whether the ad has been withdrawn or changed. Both reports identify the woman in the ad as the mother of Amy Acton, and the accounts of Acton's childhood are presented as a separate element of the coverage.
