LAS VEGAS, Nevada (AP) -- Sen. Hillary Clinton has agreed to attend a Nevada forum for Democratic presidential candidates later this month, state party officials said Tuesday.

Clinton joins five other presidential hopefuls already confirmed for the Feb. 21 event in Carson City: Sens. Joe Biden of Delaware and Chris Dodd of Connecticut, former Iowa Gov. Tom Vilsack, former New Mexico Gov. Bill Richardson and former Alaska Sen. Mike Gravel.

Billed by as a kickoff to Nevada's new early 2008 caucus, the forum faced some resistance from top-tier candidates.

Representatives for Clinton, Sen. Barack Obama and 2004 vice presidential nominee John Edwards complained last week to national party officials about the number and early timing of forums and debates scheduled in Nevada and other key states.

Nevada's caucus was moved to Jan. 19, between Iowa's first-in-the-nation caucus and the New Hampshire primary, as a way for minority and union voters in the West to get a say in picking the Democratic nominee. However, the state has not yet been showered with attention from the candidates.

Nevada Democratic Party spokeswoman Kirsten Searer said some candidates also had expressed concerns about the format of the forum, and the party agreed to accommodate them. Candidates will appear on stage individually, give a statement and answer a series of questions posed by a moderator, Searer said.
