*A rep for George W. Bush says the former president has declined an invitation from President Barack Obama to attend an observance at New York’s ground zero.

Obama plans to visit the site of the destroyed World Trade Center towers Thursday in the aftermath of a Navy SEALs raid that killed Osama bin Laden. The al-Qaida attack, which killed about 3,000 people, occurred in the early months of Bush’s presidency in 2001.

The spokesman, David Sherzer, says the former president appreciated the offer to attend but has chosen to remain out of the spotlight during his post-presidency.

Former Alaska Governor Sarah Palin gives a thumbs up after speaking at a fund raiser at Colorado Christian University in Lakewood, Colo., on Monday, May 2, 2011. The event raised money for a charity for families of fallen service members.

Meanwhile, Alaska’s former governor Sarah Palin took time out to thank the president for the death of Osama bin Laden – President George W. Bush, that is.

In delivering a speech in Colorado on Monday night, she said, “Yesterday was a testament to the military’s dedication in relentlessly hunting down the enemy during many years of war. And we thank our president. We thank President Bush.”

According to multiple reports, Palin acknowledged President Obama in her remarks, though not by name.
