Democrats will hold six presidential debates starting Oct. 13 in Nevada.

That's according to the Democratic National Committee, which released the debate plans as Republicans prepare for their first debate Thursday evening.

Four debates are planned for early primary states in advance of the Iowa caucuses on Feb. 1.

That decision has already prompted complaints from candidates trying to challenge front-runner Hillary Rodham Clinton for the nomination.

Dates for the final two gatherings are not yet set. But the committee says they will be in February or March.
