14th. Amendment to the U.S. Constitution
Section 3. No person shall be a Senator or Representative in Congress, or elector of President and Vice President, or hold any office, civil or military, under the United States, or under any State, who, having previously taken an oath, as a member of Congress, or as an officer of the United States, or as a member of any State legislature, or as an executive or judicial officer of any State, to support the Constitution of the United States, shall have engaged in insurrection or rebellion against the same, or given aid or comfort to the enemies thereof. But Congress may by a vote of two-thirds of each House, remove such disability.
If this provision was observed, it would disqualify most of the liberals living along the Mexican border that help out illegals in the Congress, and possibly disqualify for life Ted Kennedy, who provides aid and comfort to our enemy in the Middle East.
Kennedy could be a possibility (not that Congress would DO it), but as far as the others are concerned, Congress would have to go through the Constitutional process of declaring war on all the countries the illegals COME from before the 'aid and comfort' clause could be used. :(
