President George W. Bush signed the Secure Fence Act of 2006 into law "approved $50 Billion for the wall"
WHERE IS THAT MONEY?
On October 26, 2006, U.S. President George W. Bush signed the Secure Fence Act of 2006 (Pub.L. 109–367) into law stating, "This bill will help protect the American people. This bill will make our borders more secure. It is an important step toward immigration reform."[1]
The bill was introduced on September 13, 2006, by Congressman Peter T. King, Republican of New York. In the House of Representatives, the Fence Act passed 283–138 on September 14, 2006.[2] On September 29, 2006, the Fence Act passed in the Senate 80–19. The fencing built under the 2006 act was not the first border fencing in the United States. The U.S. Border Patrol first began to erect physical barriers in its San Diego sector in 1990.[3] Fourteen miles of fencing were erected along the border of San Diego, California, and Tijuana, Mexico.[4][5]
