HONOLULU -- President Barack Obama signed a wide-ranging defense bill into law Saturday despite having "serious reservations" about provisions that regulate the detention, interrogation and prosecution of suspected terrorists.
The bill also applies penalties against Iran's central bank in an effort to hamper Tehran's ability to fund its nuclear enrichment program. The Obama administration is looking to soften the impact of those penalties because of concerns that they could lead to a rise in global oil prices or cause economic hardship on U.S. allies that import petroleum from Iran.
In a statement accompanying his signature, the president chastised some lawmakers for what he contended was their attempts to use the bill to restrict the ability of counterterrorism officials to protect the country.
Administration officials said Obama was signing the measure only because Congress made minimally acceptable changes that no longer challenged the president's terrorism-fighting ability.
"Moving forward, my administration will interpret and implement the provisions described below in a manner that best preserves the flexibility on which our safety depends and upholds the values on which this country was founded," Obama said in the signing statement.
Signing statements allow presidents to raise constitutional objections to circumvent Congress' intent.
During his campaign for the White House, Obama criticized President George W. Bush's use of signing statements, and promised to make his application of the tool more transparent.
Obama's signature caps months of wrangling over how to handle captured terrorist suspects without violating Americans' constitutional rights.
