For the last 3 years, I've been a member of the anti-poverty advocacy group ONE, cofounded by U2's Bono. It's a real shame that Matt Patterson op-ed ("U2: Great music in the service of a dubious charity," June 21 ) inaccurately portrayed the work of this effective and nonpartisan organization that works with elected officials from both sides of the political aisle and with people from all walks of life to push for results-based, cost-effective programs that are saving millions of lives.

In all my time with ONE, they have only ever asked me for my voice and never my money. I'm proud of my work with ONE to engage and educate the Baltimore community about America's leadership in the world's poorest countries that have saved more than 15 million kids lives and put more than 46 million more children in school over the last decade.

On behalf of the more than 30,000 Maryland ONE members who dedicate their time and voices to fight for those living on less than $1.25 a day, I encourage Baltimore Sun readers to go to ONE.org to learn more about our work. We're not asking for your money, we're asking for your voice.
