President Biden this week issued a Proclamation (full text) declaring today "a National Day of Thanksgiving" and saying in part:
Thanksgiving provides us with a time to reflect on our many blessings — from God, this Nation, and each other. We are grateful for these blessings, even — and especially — during times of challenge.
... Just as 400 years ago when the Pilgrims were able to celebrate a successful first harvest thanks to the generosity and support of the Wampanoag, today we too express our gratitude for those who have helped us get through this difficult past year.
