Donald Trump and Hillary Clinton will meet for the last 2016 presidential debate Wednesday in Las Vegas.
Both candidates face challenges as the often nasty race for the White House moves into its final weeks.
For Clinton, a new round of hacked emails has left voters questioning again her trustworthiness when they seem to show what she says in private is not the tone she takes in public.
For Trump, the controversy over degrading remarks about women and accusations of sexual misconduct and the suggestion that the election could be rigged, continues to dominate his campaign.
The debate begins at 9 p.m. (ET) and lasts for 90 minutes without commercial interruption. Chris Wallace of Fox News is the moderator for the debate.
The debate will be divided into six 15-minute segments covering topics picked by Wallace. Both candidates will have 2 minutes to respond to a question and then another chance to respond to their opponent. Wallace will use the leftover times to expand on the discussion topic.
The six topics will be immigration, entitlements and debt, the Supreme Court, the economy, foreign policy, and each candidate's fitness to serve as president.
