With a 2nd face-to-face showdown between Vice President Kamala Harris and former President Trump unlikely, there's a lot on the line in the vice presidential debate with five weeks until Election Day

The only scheduled debate between the vice presidential nominees on Tuesday night – five weeks before Election Day – may also serve as the final word for the campaigns of Vice President Kamala Harris and former President Donald Trump before a large audience on national television.

Tim Walz of Minnesota and Republican Sen. JD Vance of Ohio will go head-to-head on Tuesday for the first and only scheduled vice presidential debate. Here's when and how to tune in. Stakes are high for the CBS News moderators following some of the backlash ABC News moderators got from Trump and conservatives after the September presidential debate.

Sen. J.D. Vance (R-OH) and Gov. Tim Walz (D-MN) are set to battle Tuesday for their only scheduled debate ahead of the November elections. The debate, hosted by CBS, comes three weeks after former President Donald Trump and Vice President Kamala Harris had their only scheduled debate.
