Former Alaska Gov. Sarah Palin (R) referenced George Orwell Tuesday in a tweet slamming President Obama ahead of his upcoming speech on Iraq.

"Obama speech tonite may make u dig out ur old Orwell books so rewritten history can be deciphered, depending on who gets credit 4 Iraq surge," she said.

In Orwell's landmark novel 1984, the protagonist rewrites historical documents to suit the changing political circumstances of a dystopian post-war society.

Republicans like House Minority Leader John Boehner, House GOP Conference Chairman Mike Pence (Ind.), and now Palin have already taken the opportunity to push back ahead of Obama's speech, scheduled for 8 p.m. Tuesday evening.

Boehner and Pence have both criticized the president for opposing the troop surge in 2007, a move many say turned the tide for the Iraq effort as a whole.

They, along with Palin, accuse him and other Democrats of taking credit for its success.

Obama will deliver the address from the Oval Office, and is expected to praise political progress in the war-torn country and thank troops for their service.
