Russia Attacking Ukraine tonight deeply saddens me. I have a wonderfully talented technology team of 100 people in Kyiv and we are trying to keep everyone safe.

Chauvin Trial Concludes
Just under a year ago George Floyd was murdered in police custody under the knee of Derek Chauvin. Today our whole family gathered around as news of a verdict announcement in the murder trial was made just a day after jury deliberation started. We all watched history as a guilty verdict was announced on each of the three charges.
This isn’t the end, but is an important step as our community reckons with racism. I found myself on the verge of tears at the announcement, relieved of some anxiety and hopeful about our ability to learn, get better, and move forward.
I’ve went back to my thoughts on Floyd’s killing and I am so appreciative of the conversations and learning that has occurred. With that said, I’ve also gained a better appreciation for how much work there is to be done.
I think it is time that the city memorialize George Floyd Square, as a tribute to what will be an inflection point toward a better community for all Minnesotans.

Record growth in COVID-19 spread. Hospitals are full. So far deaths have not increased as much because the amazing medical profession has learned a lot in the field. However, when hospitals are full will we lose that benefit?
