Nicole Kidman wins best actress in limited series at Emmys

Kidman won for her role in the HBO series "Big Little Lies," and she thanked co-star Reese Witherspoon saying she would not have won if not for her.

Moments earlier, Riz Ahmed won the Emmy Award for best actor in a limited series for his role on "The Night Of."

Both actors used their speech to support personal causes.

Kidman says of the series, "We shone a light on domestic abuse. It is a complicated, insidious disease."
