During the early years, Coldplay became widely known in the media for giving 10 percent of the band's profits to charity, which they continue to do. Bass guitarist Guy Berryman said, "You can make people aware of issues. It isn't very much effort for us at all, but if it can help people, then we want to do it." The band also asks that any gifts intended for them are donated to charity, according to a response on the FAQ section of Coldplay's website. Martin spoke out against the U.S. invasion of Iraq in 2003, and endorsed the United States Democratic presidential candidates John Kerry and Barack Obama in 2004 and 2008 respectively.
