US: G8 food security pledges not final, may be $15 bln

L'AQUILA, Italy, July 9 (Reuters) - A top White House adviser said on Thursday that G8 pledges on food aid were not final and still "bouncing around" but could end up being around $15 billion over three years.

The U.S. contribution to that effort could be around $3 billion over three years, deputy national security adviser Denis McDonough told reporters.
