Chelsea Clinton narrates a soft and sweet tribute slideshow to her mom, asking supporters to sign an e-card in honor of Mother's Day.

"I'd like to tell you about my mom," she begins, saying that no matter what, "She's always been, and continues to be my biggest fan."

The former first daughter tells supporters her mom taught her the values of self-confidence, kindness and compassion, all things passed on through three generations starting with Dorothy Rodham.

"And remember your little girls can be anything they want to be in America when they grow up, even if it's to be the second woman president," she says in closing. "Happy Mother's Day."

In similar spirit, the campaign has posted this Web video from a recent event with the three women.

UPDATE: The campaign also pushed the holiday last Mother's Day.
