ABC News' moderators did not ask the candidates about climate change or anti-choice domestic terrorism during the December 19 presidential debate, but did find time to inquire about whether the role of the presidential spouse should change.

On November 27 a gunman killed three at a Planned Parenthood clinic. He subsequently said he was trying to ensure there were “no more baby parts” and described himself as a “warrior for the babies” in court. The attack started a debate over the link between violent rhetoric directed against women's health providers and terrorist attacks on those clinics.

On December 12, leaders from every country in the world struck a historic climate change agreement in Paris to reduce fossil fuel emissions.

Moderators David Muir and Martha Raddatz did not raise either of these topics during the debate, but did find time to ask all three candidates about the role their spouses would have if they were elected. CNN's moderators previously ignored both the Planned Parenthood attack and the climate agreement during the December 15 Republican primary debate.
