CBS WASHINGTON — The showdown between President Trump and Democratic presidential nominee Joe Biden in the first presidential debate Tuesday quickly devolved into interruptions and name-calling as the two candidates went head-to-head on issues including the coronavirus crisis, the economy and the Supreme Court.

Moderator Chris Wallace of Fox News sought, with much difficulty, to corral the two presidential hopefuls into discussing their plans to revive the U.S. economy amid the ongoing coronavirus pandemic and convince the American people why they should be trusted in the Oval Office.
