US presidential debate: Donald Trump 'satisfied' with final performance

Republican presidential nominee Donald Trump expressed satisfaction with his performance in the last presidential debate against rival Democrat Hillary Clinton.

"That was really exciting. Made all of my points. 'Make America Great Again'," tweeted Trump minutes after debate ended.

The 90-minute debate that took place at the University of Nevada's Thomas and Mack Centre, and comes 20 days ahead of the November 8 election, was moderated by Fox News journalist Chris Wallace.

The candidates thrashed out issues from abortion rights to gun control to the battle against the Islamic State.

They clashed on matters of policy -- foreign and domestic. They even differed on whether they would accept the results on November 8, with Trump saying he would "take a wait-and-see approach" and Clinton calling that "horrifying", reported ABC News.
