Kamala Harris and Doug Emhoff delivered Valentine's Day cookies to DC hospital workers

• Kamala Harris and Doug Emhoff made a Valentine's Day cookie delivery to DC hospital workers.
• Harris and Emhoff apparently added handwritten notes on the sweets.
• The Bidens displayed a "Valentine to the country" with the first lady's White House installation.

Ahead of Valentine's Day, Vice President Kamala Harris and second gentleman Doug Emhoff on Saturday visited a veterans hospital in Washington, DC, to hand-deliver baskets of cookies to its workers.

"This Valentine's Day weekend, our hearts are with the health care heroes working around-the-clock to support our country during this difficult time," Emhoff wrote on Twitter of the visit to the VA Medical Center.

Emhoff wrote that he and Harris visited the hospital to meet Denis McDonough, who was recently confirmed as the new US Secretary of Veterans Affairs, and his wife, Kari.

Harris and Emhoff included handwritten notes on the sweets, which read: "Have a sweet Valentine's Day! We appreciate you. Kamala & Doug," according to People's Karen Mizoguchi.

So far this year, the gesture of delivering cookies seems to be a popular one among both the first and second families. In January, for example, first lady Jill Biden made a surprise visit after Inauguration Day outside the US Capitol Building to bring chocolate chip cookies to National Guard members stationed there.

"I wanted to come today to say thank you to all of you for keeping me and my family safe," the first lady told National Guard members on January 22. "I'm a National Guard mom. Thank you from President Biden and from the entire Biden family. I truly appreciate all that you do."

President Joe Biden and Jill got in the Valentine's Day spirit, too.

The Bidens made an impromptu appearance on Friday outside the White House, where the first lady's life-size conversation hearts were on display. Biden's office said that the first lady made the installation as a "Valentine to the country."

The decorations showed words like "unity," "family," "strength," "compassion," and "healing."

"I just wanted some joy," Jill Biden told reporters. "With the pandemic - everybody's feeling a little down, so it's just a little joy, a little hope, that's all."

The first lady also shared a picture of a pre-Valentine's Day outing where she visited a local bakery to buy sweets for the holiday.

"Shhh - don't tell Joe!" she wrote on Twitter after stopping by The Sweet Lobby.
