Former Alaska governor Sarah Palin is set to announce Tuesday that she has signed on to the Defund Obamacare movement.

"Forced enrollment in Obama's 'Unaffordable Care Act' is weeks away," Palin says in a statement to be released by the Senate Conservatives Fund and shared early with Post Politics. "This beast must be stopped -- by not funding it. Today, Todd and I joined with many of our fellow citizens to urge those in the U.S. Senate to not fund Obamacare."
