"We should also remember that the congressional resolution passed immediately after September 11th, which I supported, authorized military force only against those directly responsible for the attacks-"The first line of the Congressional Resolution mentioned above:
"To authorize the use of United States armed forces against those responsible for the recent attacks launched against the United States."
I don't see how you can call Dr. Paul a liar in this case.
But the wording of the actual resolution is what counts. That resolution gave Bush the power to go after anyone he believes planned or aided, or harbored. That is much more than directly involved.
