In the interview on Thursday with CNN anchor Dana Bash, Harris sought to show she is in command of the issues and give Americans a sense of her policy positions with little more than two months until Election Day on November 5.
Harris said she would renew a push for comprehensive border legislation that would tighten migration into the United States, and vowed to "enforce our laws" against border crossings.
"We have laws that have to be followed and enforced, that address and deal with people who cross our border illegally, and there should be consequence," Harris said.

She also hewed closely to President Joe Biden's strong support of Israel and rejected calls from some in the Democratic Party that Washington should rethink sending weapons to Israel because of the heavy Palestinian death toll in Gaza.
She said she supports a strong Israel but "we must get a deal done" to get a ceasefire in the Gaza conflict.
"No, we have to get a (ceasefire and hostage) deal done," Harris said when asked if she would withhold weapons to Israel. She has been Biden's vice president since the start of his administration.
Harris, joined by her vice presidential running mate, Minnesota Governor Tim Walz, also said she would like to add a Republican to her cabinet if she wins the election.
"I think it's important to have people at the table when some of the most important decisions are being made that have different views, different experiences. And I think it would be to the benefit of the American public to have a member of my cabinet who was a Republican," she said.

Since becoming the Democratic candidate for president last month, Harris has surged in the polls, brought in hundreds of millions of dollars in campaign donations, and had a series of forceful campaign speeches.
She leads Trump 45 per cent to 41 in a Reuters/Ipsos poll published on Thursday that showed the vice president sparking new enthusiasm among voters.
Some critics suggested she might be less polished in unscripted settings like a TV interview, but she appeared to make no major mistakes on Thursday.
Harris defended her and Biden's handling of inflation, saying they inherited a pandemic-ravaged economy that she said Trump had mismanaged. She said much work had been done to lower prices but that "prices are still too high."
Harris has moved more toward the centre on some issues from the time she ran for president in 2020 until she took over from Biden in July as the Democrats' choice to face Republican former President Donald Trump in the election.
She has toughened her position on migration along the southern US border with Mexico. She also no longer wants a ban on fracking, an energy production method that employs many people in Pennsylvania, one of a handful of swing states that could decide the election.
When asked about her policy shifts, Harris said: "My values have not changed."
Harris dismissed a comment from Trump in which he questioned whether she was a Black American. "Same old tired playbook," she said.
"Next question, please."
Trump, in a post on Truth Social, responded to the interview by saying: "I look so forward to Debating Comrade Kamala Harris and exposing her for the fraud she is." Trump often falsely refers to Harris as a Marxist.
Though she has taken questions from journalists on the campaign trail and been interviewed on TikTok in recent days, she had, until Thursday, not done a one-on-one interview with a major network or print journalist since Biden ended his re-election campaign on July 21 and endorsed her.
Bash, who co-moderated the June 27 debate between Trump and Biden that ultimately led to the president's departure from the race, conducted the interview in Savannah, Georgia, as Harris and Walz were on a campaign bus tour.
