Talking Points Memo had Republican Origin

The office of Mel Martinez, who unwittingly passed it to Senator Tom Harkin, according to the Washington Times.

UPDATE:  Mickey Kaus:

[Washington Post reporter Mike] Allen doesn't come off looking too good in this latest account. a) The memo was apparently not "distributed to Republican Senators by party leaders," as Allen's initial story, sent out through the Post news service to other papers, reported. It was--at least judging from today's account--handed to one Democratic senator, Tom Harkin, by one freshman Republican senator (who isn't in the party leadership); b) Allen doesn't explain why he told Howie Kurtz he "did not call them talking points or a Republican memo" when he had in fact done just that in the news service draft; c) Even the later, more "carefully worded" account Allen published in the Post itself was apparently wrong. Allen wrote

In a memo distributed only to Republican senators, the Schiavo case was characterized as "a great political issue"...

This is almost the reverse of what Allen now reports. We know the memo was distributed to at least one Democratic senator. We don't know whether it was distributed to any Republican senator other th[a]n the senator whose staffer wrote it (although it's hard to believe it wasn't given to at least some other GOP lawmakers)...
