There s been news erupting all over the place regarding what guests Donald Trump will be inviting to the last presidential debate. So far, we know he s bringing in the mom of a Benghazi victim, and President Obama s half-brother. Random, we know.Well, it seems as if the circus is about to get a new performer, because word just came in that Trump has invited someone else as well.NBC News correspondent Hallie Jackson let us all in on a little secret, and that is that Trump has invited none other than former half-term governor and failed reality TV star Sarah Palin to be his guest at the debate.So: Trump source tells me @SarahPalinUSA is an invited guest to tonight's #debate.
