Your guess is as good mine. A liberal judge who made a generalization about the Fourth Estate's precious "First Amendment" rights or something to that effect. Its all BS.
I think it's inconceivable that this judge isn't a Democrat acting on direct instructions from the party hacks who gave him his job. The private life of a politician should not be subject to FOIA requests and this matter has nothing to do with his conduct in office.
Contrast this with the unanimous refusal of SCOTUS to release the Vincent Foster pictures, although arguably that WAS a public concern.
