Presidential debate to put Kamala's skills to a test as she faces Trump

From her earliest campaigns in California to her serving as President Joe Biden's running mate, Kamala Harris has honed an aggressive but calibrated approach to debates.

She tries to blend punch lines with details that build toward a broader narrative. She might shake her head to signal her disapproval while her opponent is speaking, counting on viewers to see her reaction on a split screen.

Tuesday's presidential debate will put the vice president's skills to a test unlike any she's faced. Harris faces former President Donald Trump, who will participate in his seventh general election debate since 2016, for an event that will be seen by tens of millions of viewers just as early voting in November's election starts around the country.
