(CNN) - Tuesday night's statement from Florida's House Democrats stating their opposition to Sen. Bill Nelson's primary re-vote plan came after an unhappy meeting between that group and Nelson's chief of staff earlier in the day, according to a neutral Democratic source familiar with the talks.
A majority of the state's congressional delegation opposes both a primary re-vote and vote-by-mail, and feel Nelson was trying to dictate both without their consent. They gathered again after their unhappy meeting with Nelson's aide and released a statement stating their opposition – a move meant to send a message to the Florida senator that despite his public statements that a deal on terms he's described is imminent, the effort will not be successful if their concerns are not addressed.
"We are committed to working with the DNC, the Florida State Democratic party, our Democratic leaders in Florida, and our two candidates to reach an expedited solution that ensures our 210 delegates are seated," the delegation's statement read. "Our House delegation is opposed to a mail-in campaign or any redo of any kind."
The group is not unified in their objections – but enough are opposed to Nelson's plan to potentially short-circuit the proposal. In order for the plan to be approved, Florida leaders need to sign off before it can be considered by the Democratic National Committee.
Wednesday morning, Clinton campaign manager Maggie Williams released an open letter to her counterpart on the Obama campaign, David Plouffe, saying that both the Michigan and Florida votes - which were not recognized by the party - "were fair and should be honored." Williams indicated that a primary re-vote would also be acceptable, and said they were in contact with leaders in both states - including members of Florida's congressional delegation - to ensure that one of those two options occurred.
Florida and Michigan are both weighing options that would allow their delegations to be seated at the party's presidential nominating convention this summer. Both lost their voting privileges because of DNC penalties resulting from their decision to hold their primaries in January, in violation of party instructions. No major presidential candidate campaigned in either state.
