In addition, she said, Hillary Clinton has proven she is prepared to "protect and advance" her values if confronted by a Republican-led Congress.

"Now that I'm a mom ... this election just feels that much more important," Chelsea Clinton said.

Her daughter, Charlotte, is 17 months old, and Clinton is expecting another baby this summer.

She spoke for about 20 minutes before taking questions from about half a dozen crowd members Monday.

And while she didn't target her mother's primary opponent head-on in her prepared remarks, the first person she called upon asked for the top three reasons her mother should win the nomination over Sanders.

Clinton's response: her mom's foreign policy experience, her record as a "change maker" during a lifetime in politics and her focus beyond one or two issues like income inequality or campaign finance — two Sanders rallying cries.

Celeste Spier of Waverly, one of the first people to arrive for Monday's event, said she was already "fired up" by Sanders and "just hoping to get more excited and fired up about (Hillary Clinton) as a candidate."

"This is confirming my final decision," Spier said after the former first daughter's appearance.
