Republican President Donald Trump and Democratic rival Joe Biden battled fiercely over Trump's leadership on the coronavirus pandemic, the economy and the integrity of November's election in a chaotic first debate on Tuesday marked by personal insults, name calling and Trump's repeated interruptions.

Moderator Chris Wallace never established control of the debate. The two White House contenders talked over each other and lobbed insults in a breathtaking political brawl that made it hard for either to make a point.
