WASHINGTON — Republican vice presidential candidate Sarah Palin is set to appear on this week’s broadcast of “Saturday Night Live,” the entertainment show that has featured a popular parody of the Alaska governor by former cast member Tina Fey.

Palin will appear Saturday on the show hosted by actor Josh Brolin, who plays President Bush in director Oliver Stone’s new movie, “W.”

A John McCain campaign spokeswoman, Jill Hazelbaker, on Friday confirmed Palin’s appearance but offered no details about what the Alaska governor will say or do.

“SNL” is a popular stop on the entertainment circuit for presidential candidates and their running mates. Obama has appeared briefly on the show, and Republican presidential candidate John McCain once hosted it.
