Ok so he wants the resources and funds to focus on where the priority of issues is arising. Seems like smart business sense to me.
Some get theirs denied, some don't. This doesn't mean anything in the scope of the argument other than there is some reason some folks get denied. People get denied for all sorts of reasons that have nothing to do with vetting. And two months to get a visa may be long, but it's not the years you said it was.
The GAO report you reference as backup is, itself, using another database provided by the University of Maryland and is, conveniently, omitted from both the article and the study. So there's no way of knowing what is classified as "far right wing violet extremists". One racist crazy person who decides to get it in his head to kill a member of another race isn't a "far right wing extremist". And a "Far right wing extremist" isn't necessarily a "White Supremacist" like you claimed. Far Right wing extremists have problems with bankers, government, (like the Bundy standoff which I'm guessing was included in this but in reality has nothing to do with terrorism outside of being labeled as such by a partisan group). So again, I call horseshit. Should we go dig up all incidents of black people shooting, torturing, etc whites and call it "left wing extremism"? Of course not. It's stupid assholes who need to get thrown in jail.
What attack on Muslims would you have him comment on? Was there a mass murdering of Muslims on our continent he should have denounced? Because all I recall are the stories of Muslims and other crazies killing gays, school kids, and other atrocious acts.
So Conway made a gaffe. Holy cow, should I start pulling up all the gaffes made in the Obama administration? The Bush one? Big F'ing deal, dude.
