The Texas Democratic Party has taken an interesting step for the upcoming hybrid primary/caucus: Asking the campaigns not to sue. "It has been brought to my attention that one or both of your campaigns may already be planning or intending to pursue litigation against the Texas Democratic Party," wrote party attorney Chad Dunn in a letter. "Such action could prove to be a tragedy for a reinvigorated Democratic process."

According to party officials speaking under anonymity, the threat of a lawsuit has come from the Clinton campaign, during a conference call between the party and the campaigns. "Officials from Sen. Clinton's campaign at several times throughout the call raised the specter of 'challenging the process,'" according to one source.

Adrienne Elrod, spokeswoman for the Hillary campaign in Texas, denied the allegation and said the campaign was merely seeking a written agreement. "It is our campaign's standard operating procedure that we need to see what we are agreeing to in writing before we agree to it," Elrod said. "No legal action is being taken. We have no reason to take any legal action."

It's not clear what the campaign would be threatening to sue over, nor what issues are/were the subject of negotiations between the campaigns and the Texas Dems. We'll have more information soon.
