GOP presidential hopeful Donald Trump is expected to announce a detailed plan on what he hopes to accomplish in his first 100 days as president at a rally Saturday morning in Gettysburg, Pennsylvania.

Appearing on Fox News Friday night, Trump announced what some are calling his version of a "Contract with America," saying, "I really want to do it tomorrow. I can only say we're going to make America great again. Tomorrow, I think, is going to be a special day at a special place."

Trump is trailing badly in the Keystone State which hold 20 electoral votes.
