Bill and Melinda Gates, are touting what they sees as an investment with enormous returns — money spent to improve health care in poor countries and the millions of lives saved because of it.
"Global health money improves lives more effectively than any other spending," Bill Gates told a roundtable discussion Tuesday on a new initiative called The Living Proof Project that's being launched by Gates and his wife, Melinda.
The two were in Washington to urge policymakers and others to continue or even increase federal dollars spent on programs to fight AIDS, malaria and other diseases in underdeveloped nations.
