(CNN) - As Gov. Sarah Palin blasted the media Saturday in a tough Facebook post, her attorney delivered a strong warning to news outlets that they should not report any stories that allege the Alaska governor is leaving office because she is under any kind of federal investigation.
CNN has not reported these allegations were in any way connected to the governor's decision to leave office early.
"To the extent several websites, most notably liberal Alaska blogger Shannyn Moore, are now claiming as 'fact' that Governor Palin resigned because she is 'under federal investigation' for embezzlement or other criminal wrongdoing, we will be exploring legal options this week to address such defamation," said lawyer Thomas Van Flein in a letter (pdf) sent to reporters Saturday.
"This is to provide notice to Ms. Moore, and those who re-publish the defamation... that the Palins will not allow them to propagate defamatory material without answering to this in a court of law."
Moore could not be reached for comment, but told the Anchorage Daily News that she had not presented the claims as fact, and did not know whether or not they had merit, but merely served as a conduit for the rumors - which had been raised again in the wake of the governor's surprise announcement Friday.
"I haven't defamed the governor, I reported on speculation and rumor in Alaska. ... It's not my rumor; it's been out there for 10 months and the First Amendment protects me," she told the paper. "Even if I didn't say it's 'rumors and speculation,' I'm still protected - I would just lose credibility, which I'm not willing to do."
Van Flein also said in his letter Saturday that the Palin camp "can categorically state that we are not aware of any 'federal investigation' that has been 'pending' for the last seven years... To be blunt - this 'story' was alleged during the campaign, evaluated then by national media and deemed meritless. Nothing has changed."
The attorney delivered a withering critique of the media. "Just as power abhors a vacuum, modern journalism apparently abhors any type of due diligence and fact checking before scurrilous allegations are repeated as fact," he wrote.
"The Alaska Constitution protects the right of free speech, while simultaneously holding those 'responsible for the abuse of that right,'" he wrote. "These falsehoods abuse the right to free speech; continuing to publish these falsehoods of criminal activity is reckless, done without any regard for the truth, and is actionable."
On Saturday, Palin's message to supporters on her Facebook page alleged that a "different standard" was applied to her than to "countless others (who) leave their positions for a higher calling and without finishing a term."
"How sad that Washington and the media will never understand; it's about country," she wrote.
The Alaska governor did not participate in any public events on Independence Day, the day after her announcement that she would step down from office by the end of the month.
