Millions Watch Trump/clinton Debate

US presidential candidates Donald Trump and Hillary Clinton have clashed in their first TV debate.

The 90-minute showdown in the US overnight was an attempt to persuade undecided voters to support them. An estimated 100-million people tuned in last night, possibly making it the most watched programme ever. The debate focused on several key topics including race, foreign policy and crime. Hillary Clinton mentioned Donald Trump's tax returns - she suggested he might be deliberately keeping them secret. Donald Trump hit back at his Democratic rival. He promised to make his finances public - but only if Mrs Clinton reveals e-mails she controversially sent from a personal account when she was Secretary of State.
