Walz-Vance debate: when is it and how can I watch?

The debate between the Ohio senator and Minnesota governor will be hosted by CBS News at 9pm ET on Tuesday

Tim Walz and JD Vance will face off Tuesday night in the first - and only - vice-presidential debate before the November election. With the campaigns currently neck-and-neck in the polls, and with voting under way in some states, it's a chance for the would-be vice-presidents to introduce themselves to a wide US audience.

While VP debates don't usually tip the scales much, they could matter in a close race - and they build profiles for lower-profile politicians who will probably stay on the national scene for years to come.
