Speaking at tonight's town hall, Kamala Harris said the first thing she would do as president is pass a massive tax cut for middle class families.

It was the second time Harris referred to her tax credit proposal, tilted LIFT the Middle Class Act, or Livable Incomes for Families Today.

Earlier in CNN’s event, Harris said that she was proposing “one of the most significant tax cuts for middle class families in generations,” noting there are babies in America who are on the verge of starving and families who can’t pay their bills.

Her legislation would provide a refundable tax credit of $6,000 for married couples earning up to $60,000 a year. Single filers making up to $30,000 and single parents earning up to $80,000 would get a credit of $3,000. The credit would then start to phase out. Couples and single parents with earnings of more than $100,000 and single filers making more than $50,000 would no longer be eligible.

Unlike a typical tax credit, though, the bill would also allow taxpayers to receive the benefit -- up to $500 -- on a monthly basis.

“We have so many families in America right now that are a $500 emergency away from complete financial catastrophe,” she said.

One thing to note: This tax gift would be worth $3 trillion over 10 years, according to the non-partisan Tax Policy Center. But her suggested ways to pay for this benefit would not cover the bill, experts said.

At the same time, she jumped on the progressive Democratic bandwagon of blasting the top 1%, which her potential future opponent Sen. Elizabeth Warren has championed.

“People at the top 1% -- people who are making $10 million a year, who have $50 million a year, they need to pay more taxes,” she said to extended applause.
