On Friday night Prof. Richard Lazarus of Harvard delivered Maryland’s annual Fedder Lecture. He was spectacular and a terrific inspiration to students and alums concerned about the anti-environmental bent of the Supreme Court’s recent jurisprudence.

SO happy that my rehab has progressed so rapidly that I could return to the classroom for the end of the semester. Huge thanks to my children for going beyond the call of duty in helping with my rehab. I feel so loved by them.

Yesterday I was transfered from UM Medical Center in Baltimore to Medstar DC. This will make it easier for my kids in DC to visit me as I embark on a very long rehab process. Thank you to everyone for your support and caring.

I moved to Capital Hill in DC 46 years ago when I started my clerkship w Justice White. My kids went to public schools on the Hill and their kids also do. DC has never been safer, but we still lack voting representation in Congress. What we don’t lack is fear-mongering outsiders who dump on DC.

Sad to see that the Trump administration has politicized an important and formerly objective human rights report. Trump appointees cut sections on LGBTQ rights and government corruption and tempered criticism of El Salvador:

My granddaughter Zoey graduating yesterday from fifth grade at Watkins Elementary. Fun fact: she can sing the national anthem of Serbia in Serbian! She and her classmates sang it during a visit to the Serbian embassy. Both my children also are grads of Watkins, a great public school on Capital Hill.
