WASHINGTON, DC – APRIL 30: First lady Dr. Jill Biden participates in a tree planting ceremony on the North Lawn of the White House on April 30, 2021 in Washington, DC. In observation of Arbor Day, Biden put three shovels full of dirt around the base of a newly planted Linden tree that replaced one that was removed last month because it was accessed a risk due to decay.
