The television audience for the second debate between White House contenders Donald Trump and Hillary Clinton fell sharply from their first, record-breaking encounter, despite the drama caused by a 2005 video of Trump boasting about groping women.

Nielsen data for 11 broadcast, cable and public television channels on Monday showed that some 66.5 million Americans tuned into the bitter 90-minute debate on Sunday, well below the record 84 million that watched the first face-off two weeks ago.

The figures do not include millions more who watched the debate online, through social media or in bars and restaurants.
