NEW YORK — Koch Industries, which drew protests this year on speculation it might buy the Los Angeles Times or other Tribune Co. publications, said it is no longer interested in bidding. A spokeswoman confirmed Koch Industries would not be buying any of Tribune’s daily newspapers.
‘‘Koch continues to have an interest in the media business and we’re exploring a broad range of opportunities where we think we can add value,’’ said Melissa Cohlmia in an e-mail.
In May, union groups rallied in Los Angeles, trying to ward off a sale to the company controlled by billionaire Republican donors Charles and David Koch. Later, Tribune said it was spinning off its papers as a separate unit.
