Fact check: Photo of Republican Senate candidate Josh Mandel with Black Marines is authentic

USA Today quotes Siwei Lyu in a fact check article on a social media claim that a campaign ad showing a conservative Ohio senatorial candidate with Black Marines was doctored. Lyu, a digital forensics expert, told USA Today in an email that the original photo is too low-quality to make a reliable analysis. But common evidence of manipulation – such as splicing, unnatural boundaries and duplicate regions – is not present in the photo used in the ad, USA Today reports. "It is unlikely to me that this image was a result of photoshop editing, at least there is no clear clue suggesting (that)," Lyu said.
