Many people assumed the Schiavo memo controversy ended once Sen. Mel Martinez’s aide Brian Darling admitted he was the author of the memo.

Now an unnamed Republican insider tells Mary Ann Akers of Roll Call that Darling received help from two other (as yet unnamed) Martinez aides:

Martinez’s press secretary, Kerry Feehery, continues to insist that that Schiavo memo was written “unilaterally” by one aide.

However, a Republican source close to the situation said the claim is “preposterous.”

The source told HOH [Heard on the Hill] that he knows “for certain” that two other senior Martinez staffers helped Darling write the memo and circulate it to other Republican Senators. “Those three were really working it,” the source said.

But Feehery said, “That is not accurate.” She denied that anyone but Darling was involved in writing the memo. “As far as I’m aware,” she said, “there was one person unilaterally writing the memo.”

Although allegations made by an unnamed source about unnamed staffers do not carry much weight with me, you never know. The idea that it might have taken three people to write that misspelled, inept, largely plagiarized piece of crap boggles the mind.

Separately, an article in the Hill says that “some Democrats are following whether GOP staffers tried to convince bloggers covering the issue that the memo had Democratic origins….”

This is apparently a reference to the anonymous tipsters who told Josh Claybourn of In the Agora that the memo was written and distributed by an aide to Sen. Harry Reid. Two of the tipsters claimed they worked for Sen. Martinez; two others claimed to work for Sen. Rick Santorum. (Tipsters made similar allegations to The American Prowler.)

The dishonest tipsters, whoever they were, are guilty of misconduct more serious than that which led to Darling’s resignation. Come out, come out whoever you are.
