CHICAGO (AP) — A Chicago Sun-Times reporter isn't going to answer questions at R. Kelly's child pornography trial.

Jim DeRogatis cited an Illinois law that governs reporters' rights and the First and Fifth Amendments of the US constitution in refusing to answer questions.

DeRogatis read the statement more than a dozen times in response to questions, including whether he once made a copy of the sex tape at the centre of the trial.

Defence attorneys have said that copying the tape would have been a crime.

After DeRogatis' ten minutes on the stand, Judge Vincent Gaughan said reporters' privileges don't apply.

But the judge ruled that DeRogatis doesn't have to testify based on his Fifth Amendment rights against self-incrimination.

The First Amendment to the US constitution governs the right to Freedom of speech and freedom of the press.
