Democratic officials today announced speaking slots for a slew of House members, including the chamber’s top elected leaders, at the party’s national convention at the end of the month.

House Speaker Nancy Pelosi will address the convention on its first night, Aug. 25, as will Illinois Rep. Jesse Jackson Jr., according to a statement released by the Democratic National Convention Committee and Barack Obama ’s campaign.

The DNCC said earlier this week that Pelosi along with Missouri Sen. Claire McCaskill would speak about “the values of the Democratic Party” and efforts to reach out to new voters, particularly Republicans and independents.

Jackson, a national co-chairman of the Obama campaign, a close political adviser to Obama and a longtime friend of the presumed nominee’s wife, Michelle Obama, will “help tell Barack Obama ’s life story and vision for the future” in a nighttime speech, according to the release.

House Majority Leader Steny H. Hoyer and Democratic Congressional Committee Chairman Christopher Van Hollen, both of Maryland, are scheduled to speak the following day, as is Democratic Caucus Chairman Rahm Emanuel of Illinois.

House Majority Whip James E. Clyburn of South Carolina, the highest-ranking African American member of Congress, is set to address the convention on its third night.

Speaking slots were announced Saturday for several other House members, including Xavier Becerra and Linda Sanchez of California and Robert Wexler of Florida, who were early and fierce supporters of Obama in the Democratic primary.

But those who backed New York Sen. Hillary Clinton were not shut out. Rep. Nydia Velazquez of New York, one of the last lawmakers to get behind Obama, is scheduled to speak on the second day of the convention.

Reps. Mike Honda of California and Tammy Baldwin of Wisconsin, and Del. Eleanor Holmes Norton , D-D.C., were also named as speakers.

An unlisted set of Democratic contenders for House seats will also speak, officials said in their release.

“House members and House candidates have been advocating a strong message of change for America since the 2006 election,” Pelosi said in a statement. “As the people’s representatives in Congress, it is our duty to hold the White House accountable to the needs of Americans who are struggling to get by. ”
