    Words are clearly not enough but my heart has been breaking for all of the violence, destruction and devastating impact to the Israeli people including family members of mine. It is important that we all stand with Israel and not lose hope for a brighter day for all ahead.

    It's a new dawn for San Francisco kids! Couldn't be more optimistic for the future of @SFUnified in the hands of these capable, dedicated women w/ the right priorities (fiscal solvency, Superintendent hire, learning loss) in mind. Well done, @LondonBreed & thank you @recallsfboe!

    Today marks the 100th day since my cousin Danny was wrongly detained in Myanmar simply for doing his job as a journalist. Today, we call on Myanmar to release Danny on humanitarian grounds, and allow him to come home to us. 1/6 #BringDannyHome
