Former Alaska Gov. Sarah Palin (R) called the leak of thousands of sensitive diplomatic cables "treasonous" on Monday and wondered why the government could not prevent it.

"Inexplicable," she tweeted of the situation. "I recently won in court to stop my book 'America by Heart' from being leaked, but US Govt can't stop Wikileaks' treasonous act?"

Palin joins several lawmakers â€" Sens. Lindsey Graham (R-S.C.) and Claire McCaskill (D-Mo.) and Rep. Pete King (R-N.Y.) â€" who have already condemned the leaks and called for the prosecution of those responsible. 

U.S. Army Pvt. Bradley Manning, an intelligence analyst, was arrested in May 2010 in connection with a previous leak of Pentagon documents and is suspected to have participated in Sunday's release. WikiLeaks has previously denied any connection to him.

Palin's own lawsuit, which she references in her tweet, was won by publishing house HarperCollins and directed Gawker Media to remove leaked images of America by Heart ahead of its release. A hearing is scheduled for Tuesday.
