Q: Last week, Secretary of State John Kerry was in a Senate hearing trying to get financial support to fight ISIL. There were many anti-war protesters wearing CodePink T-shirts. What is CodePink and why was its members allowed to wave anti-war signs behind Kerry?

—William McKee Jr., Flowery Branch

A: CodePink is a movement initiated by women that is working to stop "U.S. funded wars and occupations, to challenge militarism globally, and to redirect our resources into health care, education, green jobs and other life-affirming activities," according to the group's website (www.codepink4peace.org).

CodePink protested during Senate Armed Services Committee hearings last week, disrupting the proceedings and leading Capitol police to escort several members of the group from the room. Congressional hearings generally are open to the public. Kerry, a Vietnam War veteran and former anti-war protester, said: “Code Pink was started by a woman and women who were opposed to war, but who also thought that the government’s job was to take care of people, and to give them health care and education and good jobs. If that’s what you believe in, and I believe it is, then you ought to care about fighting ISIL.”
