The president thinks the war on terror gives him carte blanche to go outside of the law.
It is not debatable whether the president can order electronic eavesdropping once Congress has passed a law making it criminal to do so. It is impeachable. The fact that we are sitting in 21st century America debating the issue of presidential power is ridiculous to me.
The President decided that he was no longer running the country as a civilian President. He issued a military order giving himself the power to run the country as a general.
