Lawmaker yields as antiwar group turns up heat
http://www.pww.org/article/view/7265/BALTIMORE – Members of Baltimore Pledge of Resistance went to the district office of Rep. Ben Cardin (D-Md.) June 17 to demand that he speak out against the Iraq war. The group met for several hours with Cardin’s chief administrative aide Chris Lynch.
Cindy Farquhar told Lynch she was “disappointed” that Cardin did not sign on to the Woolsey Amendment, named for Rep. Lynn Woolsey (D-Calif.) requiring President George W. Bush to announce an “exit strategy” to bring U.S. troops home from Iraq.
“We’re long past the idea that providing a better helmet is ‘supporting the troops,’” she said. “We are also asking him to join in pursuing the investigation of the Downing Street Memo. There are 120 House members who have signed Conyers’ letter to Bush on that memo.”
Lynch asked, “What does the Conyers’ letter do?”

A couple hours later he agreed to sign Conyer's letter, endorsed Rep. Pelosi’s timetable for withdrawal from Iraq, and said he would call for the closing of the U.S. Detention Center at Guantanamo Bay. He said he wanted to meet with the group again to discuss whether he would support future funding for the war.
