A dozen big-name business leaders, including lifelong Republicans and independents, say they won't support real estate mogul Donald Trump for president.
They say he would be bad for the economy, and they question how successful he's been as a businessman.
``For sustained investment, economic growth and job creation, American business needs as much predictability, reliability and stability in our government as possible,'' they write.
``Donald Trump is simply too reckless for American business.''
A copy of the letter was given to The Associated Press ahead of the group's push for others to sign on, as well as the release of the group's new website on Friday.
It comes on the heels of an open letter by more than 30 former GOP members of Congress condemning the Republican presidential nominee as ``disgraceful.''
Signatories of the latest letter include Wikipedia founder Jimmy Wales, famed chef Jose Andres and Carlos Gutierrez, US secretary of Commerce under President George W Bush and the former chief executive officer of the Kellogg Company.
