Did not hear this story -- if it's true -- on any network, or from any other media outlet. Even the shooting in Colorado wouldn't have kept this from being reported.
I did hear about the Egypt one... I was tired last night so I did not fully read the article. I assumed you were referring to the shoes and tomatoes. I agree the shooting in Colorado would have not suppressed this if it is true.
Something else would be going on here. The article seems to speculate it is to prevent embarrassment to Israel. I do not see that being true since embarrassing Israel is not a concern of this administration.
If Israeli terrorists attacked our Secretary of State in an assassination attempt, it is not an "embarrassment". If this happened, and the administration does not want to reprimand Israel, because it may alienate some voters, no wonder they want it covered up.
