I have intense respect for the separation of powers established by our Constitution, and I am fiercely protective of that privilege. But I also believe that no one is above the law--and that includes elected Members of Congress.
Based on the information that has been made public, it seems to me that the Justice Department had ample probable cause to think Louisiana's William Jefferson was involved in accepting bribes or other abuses of power. They had a legal search warrant and executed it on his office. That seems reasonable.
Not even a MOC is above the law. It is true that the Constitution prevents their arrest on lower crimes but they are not protected from felonies.
I am amazed at the outcry from both sides of the aisle claiming that this violates the separation of powers.
