President Donald Trump called Britain's Queen Elizabeth II "a great and wonderful woman" on Twitter, after the Queen recorded a rare televised address to the nation broadcast on Sunday.
The Queen typically only speaks to the public during her annual Christmas message, or when there is a new parliament installed.
The Queen's message: She urged unity and offered reassurance for the nation during her speech.
"Together we are tackling this disease, and I want to reassure you that if we remain united and resolute, then we will overcome it," the Queen said. " I hope in the years to come everyone will be able to take pride in how they responded to this challenge."
She thanked those who were staying at home and following social distancing rules, as well as frontline workers and medical staff.
Contrast in the US: Trump's praise of the Queen comes as the US struggles with its own outbreak, and as the President faces sharp criticism for his handling of the crisis.
He has sent mixed messages to the public over the past month, offering misleading information on testing, ventilator supply, and the pandemic's timeline.
Trump has also contradicted medical and scientific experts on his own White House task force, and urged the economy to resume operations by Easter -- which is this coming weekend.
"We have to open this country up," he said last week -- even as doctors warn the nation will see a massive spike in cases if Americans return to crowded workplaces or events.
