The Speaker Lineup for Night 2 of the Democratic National Convention

A popular former president, the most powerful Democrat in the U.S. Senate and one of the country’s leading left-wing voices will make the case for Vice President Kamala Harris on the second night of the Democratic National Convention in Chicago.

Former President Barack Obama and his wife, Michelle, will close Tuesday’s programming, with Mr. Obama headlining the evening in the city where he got his political start. Senator Chuck Schumer of New York, the majority leader, and Senator Bernie Sanders, the progressive Vermont independent, will speak earlier in the night.

The program includes a handful of anti-Trump Republicans, family members of prominent Democrats, lawmakers and other Democratic officials. Doug Emhoff, the husband of Ms. Harris, is scheduled to speak just before the Obamas. The lineup also includes Jason Carter, a grandson of former President Jimmy Carter, who has said he plans to vote for Ms. Harris this fall after his 100th birthday, according to his family.

Here are some of the most notable names in the lineup:

A roll call and remarks by the Minnesota and California delegations are scheduled for the 8 p.m. hour.
