Hello, Yupette,
The Adults in Virginia, Maryland, and DC politics have heard too many excuses from Jim Graham and Chris Zimmerman for Metro's poor performance. They are seeking to "sunset" both for having been on the WMATA Board too long with WMATA's performance and service quality gradually deteriorating. The recent escalator incidents were apparently the last straw. Other current WMATA members may follow Graham and Zimmerman into retirement. Thanks for your blog.
