Feb 01, 2008 — New rules took effect yesterday at the international border with Canada. Motorists entering the United States now must provide proof of citizenship, like an original birth certificate, in addition to a drivers license. Lawmakers from across the northern border region, including Senators Clinton, Schumer, and Leahy and Congressman John McHugh, have written letters to Department of Homeland Security chief Michael Chertoff. They asked Chertoff to put off the new rules until June 2009, a date Congress voted for implementation of a passport requirement at the border. McHugh told David Sommerstein Thursday he's not happy at all.
