After initially declining President Barack Obama's May offer to accompany him at memorial services at Ground Zero, President George W. Bush has changed his mind, saying he will stand side-by side with the commander-in-chief to commemorate the 10th anniversary of the Sept. 11 attacks, Mayor Michael Bloomberg said.

New York Gov. Andrew Cuomo and New Jersey Gov. Chris Christie, as well as former Gov. George Pataki and former Mayor Rudy Giuliani- - who were both in office at the time -- will be in attendance. And according to Mayor Bloomberg "that's it."

"This cannot be political," Bloomberg said on his morning radio show on WOR710 Friday. "There are an awful lot of people who would like to participate, and you just cannot do that once you open it up."

In line with the opening of the 9/11 memorial, which will open 10 years to the day, the names of every victim, including those who died at the Pentagon and in Shanksville, Pennsylvania., will be read out for the first time since the events took place, and all will be listed at the memorial, The Huffington Post reported a City Hall spokeswoman saying. Previously, only the names of the New York City victims were read.
