The Democrats are very good liars.
With Benghazi they are using a two-layered lie to cover their criminal activities.
If the first layer lie is uncovered, then the second layer lie will provide them some time to cover up.
First Layer Lie - The attack at Benghazi was caused by a video.
This lie was to gain time for the Democrats. It worked. Obama was re-elected and it is only now, four years later, that the second lie must be drug out.
Second Layer Lie - The Democrats overthrew the government of Libya and had Qadaffi killed because they wanted to capture Libyan weapons to send to the rebels in Syria.
The Democrats overthrew the government of Libya and had Qadaffi murdered in order to grab the wealth of Qadaffi and Libya.
Not quite. Though that was a secondary order effect, the overthrow of Khadaffi was to secure a nation/haven for the Moslem Brotherhood.
