It is my suspicion that the Koch Brothers must be enjoying the attention generated by their possible newspaper purchases too much to stop.

After the Los Angeles Times reporters threatened to leave in the wake of a purchase by these two billionaire entrepreneurs, one Duke University student threatened some campus activism if the sale went through.

A Duke University student has threatened “student action” if billionaire brothers Charles Koch and David Koch purchase a host of well-known newspapers owned by the Tribune Company, including the Chicago Tribune and the Los Angeles Times.

The ambiguous warning came after the student, senior Lucas Spangher, talked this week for 40 minutes with Duke trustee Bruce Karsh, reports The Chronicle, Duke’s student daily. Karsh is also the president of Oaktree Capital Management, the largest Tribune Company debt holder since the company exited bankruptcy at the end of 2012.

Karsh, a Duke alum, called Spangher from London at midnight after Spangher had contacted him. The transatlantic chat left the Duke senior disgruntled.

“The conversation was fairly unproductive or negative,” Spangher told The Chronicle. “His primary purpose for calling me was to explain his side of the story rather than listening to my arguments.”

Karsh presides over a $77.1 billion global asset management firm and donated $50 million to Duke in 2011.

According to Spangher’s bio at Takepart, he really likes green energy and once won second place in an obscure science competition. He also used to be a columnist for The Chronicle.

Charles and David Koch are titans of American industry who have donated large sums of money to conservative, libertarian and free-market groups.

Spangher’s goal had been to convince Karsh not to sell the Tribune’s bevy of newspapers to the Koch brothers. The senior objects to the sale because, he says, the magnates have provided financial support for academic studies that dispute climate change.

Karsh reminded The Chronicle that no buyer has stepped forward to buy the Tribune Company or the troubled media firm’s newspaper assets.

“The company (not me!) announced that it is exploring strategic alternatives,” Karsh wrote in an email. “It also said that no sale to anyone was imminent.”

Spangher remains wholly unconvinced. He worries that the sale of the Tribune Company’s newspapers to the Koch brothers will tilt coverage in those rags on the issue of climate change against his point of view.

“I told him that students are watching — Duke is aware of the situation,” Spangher told The Chronicle. “I appreciate the things he’s done for Duke, but if this goes down, there could be student action.”

A separate staff editorial also published in The Chronicle this week both parrots and expands Spangher’s argument.
