Why would the victim's family have special insights into Hillary's "true" role in Benghazi that multiple, multiple Republican investigations were unable to find? Where would they obtain that information?
And do you also have to post such exaggerations of the facts that you undermine your very argument? "thoroughly documented liar"? "I landed under sniper fire" was clearly wrong- either an intentional lie, an over-exaggerated spin or a 7-year old false memory. But compare that to just one day of Trump's current public statements! There are clearly some things Hillary has exaggerated, played down, or simply done wrong. But I find Ms. Clinton solidly within the usual politician scope of spinning things to her advantage- certainly no different from most current leaders in USA politics. And if we compare her to Trump or to many of the other Republican leaders she actually looks quite honest. In many ways this repeated use of her sniper fire comment by her opponents only highlights the lack of having much in the way of truly substantial, relevant, and proven other accusations against her.
Clinton is, in fact, probably among the most investigated current poitiicians (for these blatant political reasons). Ironically all these political investigations have served to clear Ms. Clinton of the vast majority of the allegations against her. Of course that hasn't stopped the Republications, or you, from continuing to assert these disproven allegations as if they were proven facts.
Finally- haven't I read on this very forum posts that argue that Trump is not responsible for all the white supremacists who attend his rallies? I agree- most rallies are open to anyone who is not a threat and wishes to attend. I'll make a deal with you- if a relative of the Orlando shooter wishes to attend a Hillary rally then I will not make a big deal of all the actual KKK and neo-Nazis who show up at Trump rallies.
