Story highlights The two sides have been debating more debates for about a week now

Sanders and Clinton are both set to attend CNN's Democratic town hall Wednesday in Derry, New Hampshire

Washington (CNN) Bernie Sanders' campaign on Tuesday refused to commit to a debate with Hillary Clinton for later this week until she signed off on a separate debate proposed for Brooklyn.

Sanders' campaign manager Jeff Weaver mocked Clinton in a statement, asking, "Why does the Clinton campaign object to a debate in New York City? Wasn't Secretary Clinton the senator from New York? Why is her campaign dissing the Big Apple?"

But Clinton accused the Sanders campaign of moving the goalposts on the issue.

"This is really hard to follow because when we said we would do the debate, they came back with conditions," Clinton told CNN's Wolf Blitzer earlier Tuesday. "We met the conditions. Then they said they want different conditions. We've tried to be very accommodating, but we have agreed with everything they have asked us to do."

In response, Sanders senior adviser Tad Devine objected to "the Clinton campaign dictating all the rules," and declined to say whether Sanders would take part in Thursday's debate, which would be hosted by MSNBC at the University of New Hampshire in Durham.
