News Corp. CEO Rupert Murdoch went on a bit of a Twitter tear Saturday morning, predicting a "nightmare for Israel if Obama wins" re-election and accusing the White House of "still lying about Benghazi."

The media mogul -- whose company owns Fox News, the Wall Street Journal, the New York Post and others -- said Vice President Joe Biden "threw [the] CIA under the bus" and "now [White House] throws State [Department]!" He also came down on Mitt Romney, saying the Republican presidential nominee needs to ignore personal attacks at the next debate and focus on his jobs plan:

Murdoch has been fairly free with his Twitter advice for Romney in the past: Last month he said he needed to "stop fearing [the] far right" and take more of a big tent approach to win the election. During the summer, he wondered, "when is Romney going to look like a challenger?" He subsequently defended himself from an apparent barrage of negative tweets from Romney supporters, saying, "of course I want him to win, save us from socialism, etc."

As Mediaite noted, when a Murdoch-type figure in the media espouses such clear-cut political beliefs so publicly, "the question arises as to whether these opinions will eventually trickle down through their outlets."
