CHICAGO (AP) — Two teenagers have pleaded guilty in the sexual assault of a 15-year-old girl that was streamed live on Facebook in March.

In a plea deal with Cook County prosecutors, the 15-year-olds pleaded guilty to a single count of child pornography and will be sentenced to probation. Judge Patricia Mendoza said Tuesday she would decide the length of the probation by their January sentencing.
