An anti-tax activist from upstate New York who is questioning whether President-elect Barack Obama is a “natural born citizen” eligible for the nation’s top job said Tuesday that his nonprofit group spent “tens of thousands of dollars” to get his message across in ads in the Chicago Tribune this week.

Robert L. Schulz, 69, chairman of We The People Foundation, took out ads Monday and Wednesday to raise questions about whether Obama’s Hawaii certificate of live birth is authentic.

The ads echo accusations circulated online by Obama opponents before the election. Cases challenging Obama’s citizenship have been tossed out of local courts in several states, and Hawaiian officials have vouched for the authenticity of Obama’s birth certificate, which is locked in a state vaults. Nevertheless, some conservative critics remain dubious.

Questions raised

Here are some of the allegations raised in Schulz’s ad, and some facts related to them:

• The birth form released by Obama was “an unsigned, forged and thoroughly discredited” live birth form, Schulz says.

Last summer, Obama’s campaign presented a digital copy of his certificate of live birth. After critics questioned its authenticity, staffers at FactCheck.org, a project of the Annenberg Public Policy Center of the University of Pennsylvania, said it had seen, held and examined the actual birth certificate.

• “Hawaiian officials will not confirm” that Obama was born in their state, Schulz says.

Initially, Hawaiian officials said that privacy laws prevented them from releasing a copy or confirming that Obama’s copy was authentic. But in late October as questions persisted, Hawaii’s health director and head of vital statistics reviewed Obama’s birth certificate in the department’s vault and vouched for its authenticity.

• Schulz says that legal affidavits state Obama was born in Kenya.

The affidavits that Schulz refers to are filings in the court cases challenging Obama’s citizenship.

• Obama’s paternal grandmother is recorded on tape saying she attended Obama’s birth in Kenya, Schulz says.

The group’s Web site posted what it says is a transcript of a long-distance phone conversation in Swahili and English from late October with Sarah Hussein Obama. The translator said the interview was conducted in a crowded hut, over a speaker phone that dropped the call three times, with two Swahili translators during a celebration. A copy of the recording was not provided by Schulz.

• Schulz says that “U.S. law in effect in 1961 (the year of Obama’s birth) denied citizenship to any child born in Kenya if the father was Kenyan and the mother was not yet 19 years of age.”

If a child is born in the United States — as Hawaiian officials state unequivocally that Obama was — that child is a U.S. citizen regardless of his or her parents’ nationalities. If born to an American parent outside the U.S., the law at the time would require the U.S. citizen parent to be at least 19, which Obama’s mother was not. The provisions of this law were subsequently loosened and made retroactive for government employees serving abroad and their families. It appears that this would not apply to Obama’s mother. But Hawaiian officials say the matter is academic because Obama was born in the U.S.

• Schulz says that in 1965, Obama’s mother relinquished whatever Kenyan or U.S. citizenship she and Obama had by marrying an Indonesian and becoming a naturalized Indonesian citizen.

U.S. law lists the specific acts and formal procedures necessary to relinquish U.S. nationality. The statute requires the acts be performed voluntarily and with the intention of relinquishing one’s nationality. In many instances, one must be 18 to renounce one’s citizenship. Obama moved to Indonesia in 1968 and moved back to Hawaii while still in grade school. There is no indication that Obama renounced his U.S. citizenship.

Schultz supports his argument with a reproduced Indonesian school document that states Obama’s citizenship at that time as “Indonesian.” The same document also lists Obama’s birthplace as “Honolulu, Hawaii.”

Schulz, interviewed by the Tribune on Tuesday, said his concern about Obama’s citizenship is not a partisan issue.

“We never get involved in politics,” he said of We The People. “We avoid it like the plague.”
