Sen. Kamala Harris told a crowd Monday that she would push for the federal government to rename Columbus Day “Indigenous Peoples’ Day,” a focal point for some progressives who say the holiday should emphasize the history of Native Americans instead of the European conquerer.

“Sign me up,” Harris said in response to a voter’s question of whether she would support the initiative to rename the holiday. She spoke of her own efforts in the Senate to make lynching a federal crime.

Harris, who officially launched her campaign for president last month in Oakland, drew an overflow crowd on her first town hall in New Hampshire, the site of the country’s first presidential primary. They spilled out of a church and into the snowy streets of Portsmouth to hear her deliver a campaign message of “speaking truth” and “fighting for justice,” a refrain that focuses in part on her past as a prosecutor and law enforcement official.
