DENVER -- Sen. Hillary Clinton will speak on the second night of the Democratic National Convention in a nod to her strong second-place showing in the party's presidential primary.

The DNC released its list of headline speakers Sunday afternoon.

The former first lady will speak on the second night, Tuesday, Aug. 26 -- the 88th anniversary of women's right to vote. The campaign and convention committee in a statement called her "a champion for working families and one of the most effective and empathetic voices in the country today."

The Obama campaign is trying to avoid hard feelings among Clinton's supporters at their carefully orchestrated convention. But they still haven't reached a deal on whether Clinton will be included in the roll call vote for the nomination, which could make the party appear divided heading into the final stretch of the White House race.

The presumptive Democratic nominee's wife, Michelle Obama, will open the week-long convention on Monday night, followed by Clinton on Tuesday.

The headline prime-time speaker for Wednesday will be Obama's yet to be named vice presidential nominee.

Then the convention moves across the interstate to the bigger venue at Invesco Field at Mile High for Obama's acceptance speech on Thursday night.

It happens to be the 40th anniversary of Martin Luther King's "I Have a Dream" speech.

Democratic officials say Bill Clinton is also scheduled to speak that night, but only the headliners were in Sunday's official announcement.

Spokeswoman Jenni Engebretsen said the DNCC will unveil additional convention speakers later next week.

Debate Continues On How To Recognize Clinton's Supporters

Clinton told supporters she is seeking a way for her delegates to be heard at the convention and be united after the hard-fought nominating contest.

"Because I know from just what I'm hearing, that there's incredible pent up desire. And I think that people want to feel like, 'OK, it's a catharsis, we're here, we did it, and then everybody get behind Sen. Obama.' That is what most people believe is the best way to go," she said, according to video of the remarks taken by an attendee and posted on YouTube last week.

Obama told reporters Thursday he thought the negotiations with Clinton aides had gone "seamlessly," but he also rejected the notion that there might be a need for emotional release on the part of some Democrats.

"I don't think we're looking for catharsis," said Obama. "I think what we're looking for is energy and excitement."

Advisers to the New York senator said she will almost certainly not ask to have her name placed in formal nomination at the convention to avoid a divisive vote.

Under DNC rules, Clinton must submit a signed, written request to have her name placed in nomination, accompanied by a petition signed by at least 300 delegates. Some Clinton delegates have circulated such petitions, but the effort is meaningless without Clinton's signed request.

Delegates are not formally pledged to any candidate so Clinton does not need to "release" them to Obama. The rules also say delegates may vote for the candidate of their choice whether or not the name of such candidate was placed in nomination.
