Newark Mayor Cory Booker will speak at the Democratic National Convention next month in Charlotte, N.C., President Obama’s campaign announced late Thursday night.

Booker, one of a dozen speakers the Obama campaign announced, will present the party platform to convention delegates on Sept. 4. He will be joined by Retired Army Lt. General Claudia Kennedy and Rep. Barbara Lee of California.

It is unclear what time Booker will speak, but so far, he is the only New Jersey Democrat who has been given a speaking role at the convention, which will be held Sept. 3-6. Booker co-chaired the party platform committee and his speech is an extension of that leadership role.

"We have a platform that will excite not just Democrats but the nation ... and ensure that Barack Obama will be re-elected," Booker said during a C-SPAN broadcast of committee deliberations.

One new plank in the party platform will be an endorsement of marriage equality, an issue Booker has championed for years.

"At the end of the day, it’ll maybe repel some and attract others to be more engaged," Booker told the Associated Press in Detroit earlier this month after a committee meeting. "This campaign is not going to turn on gay marriage. This campaign is going to turn on who has the best ideas for the economy."

The speech is as good an indication as any that Booker did not burn many bridges with party leaders in May when he criticized the Obama campaign for attacking Republican nominee Mitt Romney's tenure at Bain Capital.

Moreover, if Booker remains the only speaker from New Jersey, it helps distinguish him from other state Democrats possibly vying for the party’s gubernatorial nomination next year.

The other speakers listed last night included Connecticut Gov. Dannel Malloy, Philadelphia Mayor Michael Nutter and Los Angeles Mayor Antonio Villaraigosa, who is also the convention chairman.

Julian Castro, the 37-year-old mayor of San Antonio, Texas, will deliver the convention’s keynote address.

Gov. Chris Christie will deliver the keynote at the Republican National Convention in Tampa next week.
