MANCHESTER, Iowa — The campaigns of the two major candidates for the Democratic nomination have agreed to hold four more debates, sources from both the Hillary Clinton and Bernie Sanders campaigns tell BuzzFeed News. 
 
 The details — where and when — remain unresolved, the Clinton and Sanders sources said. The Democratic National Committee announced on Sunday it will sanction a Feb. 4 debate in New Hampshire and the additional debates, pending an agreement by the campaigns on the details. 
 
 “Our Democratic candidates have agreed in principle to having the DNC sanction and manage additional debates in our primary schedule, inclusive of New Hampshire this week," said DNC Chair Rep. Debbie Wasserman Schultz. "However, absent agreement on the details, we will give our campaigns the space to focus on the important work of engaging caucus goers in Iowa. We will reconvene negotiations and finalize the schedule with the agreement of our campaigns on Tuesday morning." 
 
 Both sides have agreed to attend the New Hampshire debate, moderated by NBC News' Chuck Todd and MSNBC anchor Rachel Maddow. The New Hampshire debate would take place just days before the primary there. 
 
 Disagreements between Clinton's and Sanders' campaigns over the location and timing of additional debates have already spilled out into the open, with the Sanders campaign issuing a strongly-worded statement Saturday afternoon aimed at the Clinton campaign. 
 
 "We agreed pending an agreement on three future debates in March, April and May. Unfortunately, the Clinton campaign has not accepted debates we proposed on March 3 in Michigan and April 14 in New York," Bernie Sanders’ campaign manager, Jeff Weaver said in a statement. "They apparently agreed to May 24 in California. The Clinton campaign, after not accepting Michigan, now says they want it. We are pleased to do it on March 3 before the Michigan primary provided the Clinton campaign will agree to Brooklyn, New York, on April 14. Why won't they debate in Brooklyn? What's the matter with Brooklyn?" 
 
 Clinton's campaign shot back with a press release of its own, saying, "There is nothing worse than a debate about debates." 
 
 "The people of New Hampshire wanted a debate. We said Secretary Clinton would be there,” said Clinton campaign chair John Podesta. “The Sanders campaign said their candidate would only come if we agreed to three additional debates, one each in March, April, and May. We agreed to that. The Sanders campaign further asked that these debates not take place on weekends or holidays. We agreed to that as well, and offered date windows accordingly. The Sanders campaign proposal has been met in all respects. Now they refuse to take yes for an answer, apparently because they are intent on avoiding a debate in New Hampshire. Enough of the games.” 
 
 
 
 Podesta continued, "We made the modest suggestion that one of the three additional debates take place in Flint, Michigan, to shine a spotlight on what’s happening there and in places like Flint around the country. The Sanders campaign never responded. We’re not sure why, but if they’d rather not debate in Flint, we’re certainly willing to mutually agree on three other locations.” 
 
 Aides to Sanders campaign told BuzzFeed News earlier on Saturday that they are still concerned about the timing of any additional debates, insisting that those after the Feb. 4 face-off be as high-profile and positioned for a wide audience before the key nominating contests. Sanders aides have said they want the debates to happen before contests that will award a large percentage of total delegates. 
 
 
 
 Martin O’Malley’s campaign has expressed willingness to debate any time, anywhere. 
 
 
 
 A DNC official told BuzzFeed News that the Union Leader, originally a partner of the event with MSNBC, will not be a debate sponsor in New Hampshire under any agreement reached between the party and the campaigns. As for the expanded calendar, "still waiting for final sign off more generally from the campaigns on any debate(s)," the official told BuzzFeed News via text message. ||||| The next official debate is in Milwaukee on Feb. 1, but there could be a New Hampshire event next week. | AP Photo DNC moving to assert control as more Democratic debates agreed 
 
 CEDAR RAPIDS, Iowa — If the Democratic National Committee were to sanction a Democratic debate on Feb. 4 in New Hampshire, it would likely do so without being co-sponsored by the state's largest newspaper, three sources familiar with the plans have confirmed. 
 
 Although the debate, to be hosted by MSNBC, was first proposed by the New Hampshire Union Leader, the paper would have a decreased presence at the DNC's request as the party tries to reassert control over a debate process that has become chaotic in recent days. Sources said the committee wants the Union Leader to stand down in part because it has already cosponsored a Democratic debate with ABC.

 The Union Leader would still be involved, likely by contributing some questions from the paper's subscribers, but would not be technical "co-sponsors" for branding and the like. Sources said the paper was willing to sacrifice its involvement to make sure the debate happened. The plans, the sources stressed, are still in flux. 
 
 The debate would be moderated by MSNBC hosts Chuck Todd and Rachel Maddow. 
 
 The Union Leader, MSNBC and the DNC declined to comment. 
 
 Meanwhile, Hillary Clinton and Bernie Sanders’ campaigns have agreed in principle to attend four more debates, starting with the proposed New Hampshire event next week, a Clinton campaign aide confirmed Saturday — but an exchange of statements on Saturday called the Feb. 4 date into question. 
 
 Both campaigns, and Martin O'Malley's, spent Friday negotiating with the DNC, which has not publicly weighed in on the campaigns’ requests to add the four events — one in February, one in March, one in April, and one in May — since Sanders proposed it this week. The final details are still being ironed out, and no dates or locations have been solidified. 
 
 The step forward came after days of wrangling in public and behind the scenes, as the two major Democratic candidates sought to pressure each other on the topic of adding debates. 
 
 But the Sanders campaign, with its latest statement on Saturday afternoon, suggested the New Hampshire debate won't happen unless the rest of the schedule is agreed upon. So the New Hampshire debate, at the moment, is on hold. 
 
 "After refusing for months to participate in more debates, Secretary Clinton requested that the Democratic National Committee rules be changed and that a new debate take place in New Hampshire next week," Sanders campaign manager Jeff Weaver said. "We agreed pending an agreement on three future debates in March, April and May. Unfortunately, the Clinton campaign has not accepted debates we proposed on March 3 in Michigan and April 14 in New York. They apparently agreed to May 24 in California. The Clinton campaign, after not accepting Michigan, now says they want it. We are pleased to do it on March 3 before the Michigan primary provided the Clinton campaign will agree to Brooklyn, New York, on April 14. Why won't they debate in Brooklyn? What's the matter with Brooklyn?" 
 
 Clinton campaign chairman John Podesta soon responded, suggesting that Clinton would be at the New Hampshire event regardless of Sanders' involvement. 
 
 "We are prepared to show up for a debate next Thursday and for three additional debates in the months ahead, which we can all work together to schedule. We hope Senator Sanders will be there too," he said in a statement on Saturday night. "If the Sanders campaign decides to reject the debate next week, we’ll let them answer to the voters of New Hampshire." 
 
 Shortly before Weaver's statement, Clinton had proposed a debate in Flint, Michigan. 
 
 Sanders, O’Malley, and Democratic activists had long made an issue of the previously scant debate schedule — just six events, and only four before Iowa and New Hampshire vote; trailing in New Hampshire, Clinton tried to push Sanders into agreeing to the event there after the New Hampshire Union Leader and MSNBC earlier this week announced an unsanctioned event would be held there. 
 
 Sanders responded by proposing the additional debates, which now seem likely to occur if the DNC signs on. The committee would have to waive its exclusivity clause that precludes candidates from appearing in unsanctioned debates and bars them from joining the official events if they do. 
 
 The next official debate is in Milwaukee on February 11, two days after the New Hampshire primary.
– After months of complaints, Bernie Sanders appears primed to get his wish: additional debates. The Hill reports Sanders and Hillary Clinton have reached an agreement to hold four more debates, starting with an unsanctioned-by-the-DNC event on Feb. 4 in New Hampshire. The deal was actually spurred by Clinton, who pushed for the New Hampshire debate after polls showed her trailing there, according to Politico. The next official debate was not scheduled until Feb. 11, two days after the vote in New Hampshire. Sanders agreed to the New Hampshire debate as long as three additional debates were added. "We are looking forward to four additional debates,” a Sanders campaign source tells BuzzFeed. Sanders has been pushing for more debates for months now, Politico reports. Prior to this agreement—which the DNC has yet to sign off on—there were only six scheduled Democratic debates. Dates and locations haven't been decided, but the Sanders and Clinton campaigns appear to want one each in March, April, and May. And BuzzFeed notes Martin O'Malley just wants to debate "any time, anywhere."
