Washington (CNN) - Democratic National Committee Chairman Tim Kaine plans to make what's being billed as a major announcement Wednesday about the future of the party, according to a Democratic source with knowledge of the speech.
The source tells CNN that Kaine will announce something that will excite Democrats across the country. Kaine's event comes as Democrats face the difficult task of holding onto their majorities in the House and Senate this November.
The speech, scheduled for Wednesday afternoon at George Washington University, happens around the same time that Republican National Committee Chairman Michael Steele kicks of a major bus tour in support of Republicans running in the midterm elections. But the source says that the timing of Kaine event was in the works well before the date of Steele's kickoff was announced.
