(CNN) - Sen. Mitch McConnell's campaign is seizing on a change made earlier this year in his conservative challenger's LinkedIn profile after a report stated Matt Bevin had misleading information on his online resume.
In March, The Hill reported that Bevin, a businessman with tea party ties, led readers of his profile to believe he graduated from a program affiliated with the prestigious Massachusetts Institute of Technology.
School officials, however, told the news outlet the school had no formal record of Bevin. The program in which he enrolled took place in a building owned by MIT, but it was not otherwise connected to the school.
One official told The Hill that the three-year program–"Birthing of Giants/Entrepreneurial Master's Program at MIT Endicott House"–is not an official program offered by MIT, but sponsored in part by the MIT Enterprise Forum, an alumni-created network of "loosely affiliated regional groups interested in entrepreneurship."
Bevin tweaked his LinkedIn profile after The Hill notified Bevin of its reporting, making the MIT listing more specific. The events took place in March, months before Bevin announced his candidacy in late July for Kentucky's GOP Senate primary next year.
McConnell launched a new six-figure television ad on Tuesday that recycles the campaign's attack on the businessman over questions about his financial history, while also diving into the MIT issue.
"Can you believe Bailout Bevin on anything?" the ad's narrator asks.
Bevin's team responded Tuesday morning with a photo of a certificate from the program.
"The truth? From 2006 to 2008, Matt Bevin attended the (Entrepreneurs' Organization)/MIT Entrepreneurial Masters Program," an email from his campaign stated. "That is the official name of the program as printed on the certificate he received upon finishing the program."
In the same email, Bevin said the latest ad takes "the childishness of campaign name-calling to a whole new level."
"Just when you think the lies can't get any more ridiculous, Mitch McConnell proves that he'll stoop to any level to hang on to his job," Bevin said.
The term "Bailout Bevin" used by the Senate minority leader's campaign comes from a $200,000 state grant that Bevin's company received after its his Connecticut-based bell manufacturing company and a specialty gas cylinder manufacturer, in which he had minority stake, were destroyed in a 2012 fire. According to a local newspaper article at the time, Bevin's insurance barely helped out.
The MIT attack ad is the latest punch in a round of already hard-hitting blows between the candidates. In his inaugural television ad last month, Bevin went after McConnell, the Senate's top Republican, for his "failed leadership" and aggressively targeted the senator in his speech at Kentucky's annual political speech-making event, "Fancy Farm."
McConnell's team has also been out front with a series of ads and web videos attacking the primary challenger.
