DNC Day 2 will feature array of remarks from prominent Republicans

But the DNC won't only feature speeches from Democrats on Day 2 as several Republican leaders will also offer remarks in Chicago.

Vice President Kamala Harris' campaign announced Tuesday that former U.S. Rep. Adam Kinzinger of Illinois, former Georgia Lt. Gov. Geoff Duncan and the mayor of Mesa, Arizona, John Giles, will take the DNC stage Tuesday. All are now critics of Trump.

Also speaking are former Trump White House staffers Olivia Troye, a former national security official, and Stephanie Grisham, who was a White House press secretary.

Grisham said she knows Harris will “defend our freedoms and represent our nation with honesty and integrity.”

“I never thought I’d be speaking at a Democratic convention,” she said in a statement. “But, after seeing firsthand who Donald Trump really is, and the threat he poses to our country, I feel very strongly about speaking out.”

Earlier in August, the former Trump press secretary announced her endorsement for Harris.

"I might not agree with Vice President Kamala Harris on everything, but I know that she will fight for our freedom, protect our democracy and represent America with honor and dignity on the world stage," Grisham said in a statement at the time.

Who is speaking at the DNC tonight?

Former President Barack Obama, Michelle Obama and second gentleman Doug Emhoff are headlining the DNC Tuesday. 

Along with Emhoff and the Obamas, the Harris campaign said it would spotlight “trusted messengers” from battleground states over the convention’s three remaining days. The list includes Sen. Catherine Cortez Masto of Nevada; Gov. Gretchen Whitmer, Sen. Gary Peters and Rep. Elissa Slotkin of Michigan; Sen. Bob Casey of Pennsylvania, Sen. Mark Kelly of Arizona and Sen. Tammy Baldwin of Wisconsin.

The list also includes several prominent Republicans scheduled to speak.
