The first Democratic presidential debate on January 12 was hosted by ABC and MSNBC, and the show featured both candidates.
Both candidates spoke, with Clinton and Sanders focusing on economic issues and issues of war and peace.
The candidates did not directly answer questions about the 2020 election.
While many expected the Democratic debate to be an extended, substantive debate, the debate on Jan. 12, 2020, was an extended conversation that lasted about 15 minutes, according to two sources familiar with the event.
The debate, held in Flint, Michigan, was the third and final presidential debate before the 2020 presidential election.
