Republican presidential candidate Rudy Giuliani said Thursday that he will leave his consulting firm because of the demands of his White House bid.

Giuliani was asked about his role in Giuliani Partners LLP during a campaign stop in Columbia, but said he didn't have an exact time table on when he would leave.

"I'm largely out of it and I'm pretty much going to be out of it at some point pretty soon," he said.

Giuliani Partners was founded a few months after the Sept. 11 terror attacks that thrust Giuliani into the national spotlight. The firm advises businesses and government officials on emergency preparedness, public safety, and corporate governance.

Last month, Giuliani Partners said it was selling its investment banking arm, Giuliani Capital Advisors LLC, to Macquarie Group of Sydney, Australia.

Giuliani gave no indication he is considering leaving Bracewell & Giuliani, a well-established law firm in Washington and Houston that he joined in 2005. The firm is best known for its energy company clients.

The former mayor's bid for the presidency has increased attention on exactly who his business clients are, and how those relationships might affect his political platform.
