90 minutes of fire: Trump, Clinton trade charges, insults in 2nd debate

In a presidential campaign debate filled with tension and insult, Hillary Clinton declared that Donald Trump's vulgar comments about women reveal "exactly who he is", while he accused her of attacking women involved in Bill Clinton's extramarital affairs and said she would "be in jail" if he were president.

Trump unleashed a barrage of attacks and acknowledged for the first time that he had paid no federal income taxes for many years.

The debate was the culmination of a stunning stretch in the race for the White House, which began with the release of a video in which Trump is heard bragging about how his fame allowed him to "do anything" to women.
