The Democrats control the senate and it is easy to ignore inconvenient facts. For instance. The 6th Fleet was monitoring the events in Benghazi from the beginning. The Commander had an intervention plan ready to execute within twenty minutes. He was ordered to stand down. Thus far that commander and other senior military have been silenced. The Democrat controlled Senate absolutely refused to investigate and was fully cooperating with the Obama administration to block meaningful inquiries.
And Boehner played right along by not appointing a select committee in the House.
