Los Angeles ? Arnold Schwarzenegger announced Thursday that former U.S. Secretary of State George P. Shultz would co-chair an Economic Recovery Council for his gubernatorial campaign.

It was the second major announcement in two days for the actor. On Wednesday, the campaign said billionaire investor Warren Buffett would be a financial adviser.

Buffett and Shultz will be joint co-chairs of the economic council. The appointments of Buffett, a Democrat, and Republican Shultz reflect the campaign’s attempt to assemble a diverse and bipartisan team.

The campaign will soon have an economic summit, Schwarzenegger said.

It was Schwarzenegger’s first exchange with reporters since he filed candidacy papers Saturday, and his first public appearance since attending a summer school program Monday in New York.

“I’m a very astute businessman. I know exactly what I’m doing,” Schwarzenegger said.
