Sen. Richard Shelby, R-Ala.

WASHINGTON – A U.S. senator has weighed in on the continuing controversy over Barack Obama's eligibility for office by saying he has never seen proof the new president was actually born in Hawaii.

"Well, his father was Kenyan and they said he was born in Hawaii, but I haven't seen any birth certificate," Sen. Richard Shelby, R-Ala., told constituents in Cullman County. "You have to be born in America to be president."

Where's the proof Barack Obama was born in the U.S. or that he fulfills the "natural-born American" clause in the Constitution? If you still want to see it, join more than 250,000 others and sign up now!

WND has reported on multiple legal challenges to Obama's status as a "natural born citizen." The Constitution, Article 2, Section 1, states, "No Person except a natural born Citizen, or a Citizen of the United States, at the time of the Adoption of this Constitution, shall be eligible to the Office of President."

Some question whether he was actually born in Hawaii, as he insists. If he was born out of the country, Obama's American mother, the suits contend, was too young at the time of his birth to confer American citizenship to her son under the law at the time.

Other challenges have focused on Obama's citizenship through his father, a Kenyan subject to the jurisdiction of the United Kingdom at the time of his birth, thus making him a dual citizen. The cases contend the framers of the Constitution excluded dual citizens from qualifying as natural born.
