In an interview with CBS News anchor Norah O'Donnell, Harris said her first 100 days in office should she win the election would be focused on lowering costs for American families, including her proposals on housing, small businesses and the Child Tax Credit.

"A priority in equal form is going to be what we need to do to deal with reproductive health care and reinstate the freedoms and the rights that all people should have and women should have over their own body, and then dealing with immigration, in particular, border security and bringing back up that bipartisan bill that Donald Trump killed so we can get more resources down to the border," she added.

But when asked how she'd navigate a potentially divided Congress, Harris only said she believed Congress would "work across the table" on issues plaguing most Americans.

"These are not partisan issues. Democrats, Republicans, independents deal with these issues equally, and actually don't think of think of them through the lens of the party with which they're registered to vote," she said. "So that means working across the aisle."

The former first lady repeated her passionate message on women's health being at stake this election in an op-ed published by the New York Times on Monday,

The op-ed featured excerpted remarks from her rally in Michigan on Saturday in which she blasted Trump's record on the issue in comparison to Harris', and made an appeal to men to support the women in their lives. The rally marked her first campaign appearance since her speech at the Democratic National Convention this summer.

"I am asking you, from the core of my being, to take our lives seriously," she said. "Please do not put our lives in the hands of politicians, mostly men, who have no clue or do not care about what we as women are going through, who don’t fully grasp the broad-reaching health implications that their misguided policies will have on our health outcomes."

Despite her stated aversion to partisan politics, the former first lady is ramping up her involvement in the final stretch of the 2024 campaign. She will headline a rally on Tuesday in battleground Georgia.

Harris is countering the dark and racist comments made by speakers at Trump's Sunday rally at Madison Square Garden, while the former president's campaign tries to distance itself from the comedian who referred to Puerto Rico as a "floating island of garbage."

Harris will stump in two critical counties in the battleground state of Michigan to kick off the final full week of campaigning. First, she will visit Corning's manufacturing facility in Saginaw before getting a tour at a union training facility in Macomb County.

The vice president will cap the day with a rally with her running mate, Gov. Tim Walz, in Ann Arbor. The rally will feature a concert by musician Maggie Rogers.

Trump will be in Georgia to deliver remarks at National Faith Advisory Board in Powder Springs before a 6 p.m. ET rally in Atlanta.

As of 5:45 a.m. ET on Monday, more than 41 million Americans have voted early, according to the Election Lab at the University of Florida.

Of the 41,989,199 total early votes, 21,111,171 were cast in person and 21,338,290 were balloted returned by mail.

On Monday, voters in Washington, D.C., can start casting their ballots early, in person. Almost all of the states that offer in-person early voting have begun offering it by now.
