2024 election updates: Trump, Harris hit more battlegrounds

Former first lady Melania Trump, sitting down for an interview with Fox & Friends, attempted to pitch her husband to voters.

"I think American people need to decide what they really want. Maybe some, you know, strong tweets, but everything else great for this country. So it's all in Americans people's hands on Nov. 5," she said, arguing her husband was a strong leader in terms of the economy and immigration.

Despite her lack of a role on the campaign, Melania Trump said that she supports her husband's third bid to the White House.

"I know how passionate he is to make America great again," she said.

Melania Trump was also asked some personal questions about her relationship with Trump.

"Did you fall in love then?" co-host Ainsley Earhardt asked after Melania Trump described meeting Donald Trump for the first time.

"It was a connection. It was a connection," Melania Trump responded.

"His being," she later said when asked what she loves most about Trump. "His humor, his personality, his kindness, he's, he's very special, his positivity, his energy. It's unbelievable. Yeah, so we have a beautiful relationship."

An aide to Vice President Kamala Harris' campaign provided more details about the vice president's planned visit to the border in Arizona on Friday.

Harris will visit the border city of Douglas, and deliver remarks on border security, according to the aide. She will also talk about her intention to introduce a tough bipartisan border security plan and criticize former President Donald Trump for killing the one introduced over the summer.

Vice President Kamala Harris released her roughly 80-page economic policy book on Wednesday and outlined it in a speech in Pittsburgh.

Harris spoke at the Economic Club of Pittsburgh and framed her proposals into three pillars: "lowering costs, investing in American innovation and leading the world in industries of tomorrow."

She also highlighted her plans for American manufacturing.

"The simple truth is, in America, it takes too long and it costs too much to build. Whether it's a new housing development, a new factory or a new bridge, projects take too long to go from concept to reality," Harris said. "It happens in blue states, it happens in red states, and it's a national problem. And I will tell you this, China is not moving slowly. They're not, and we can't afford to either. If we are to compete, we can't afford to either."

She attacked former President Donald Trump's record, calling him "one of the biggest losers ever on manufacturing."

"Just yesterday, he went out and promised to bring back manufacturing jobs. And if that sounds familiar, it should, in 2016 he went out and made that very same promise about the Carrier plant in Indianapolis," she said.

"You'll remember, Carrier then offshored hundreds of jobs to Mexico under his watch. And it wasn't just there. On Trump's watch, offshoring went up and manufacturing jobs went down across our country and across our economy."

Harris drew contrasts between her economic agenda and that of her opponent, Trump, in a speech in the battleground state of Pennsylvania.

Harris told an audience at the Economic Club of Pittsburgh that her economic philosophy is "rooted in her middle-class upbringing" while Trump's comes from a "gilded path to wealth."

"For Donald Trump, our economy works best if it works for those who own the big skyscrapers. Not those who build them. Not those who wire them. Not those who mop the floors," she said.

Harris has made the economy and the cost of living a focal point of her campaign in recent weeks.

To allow the middle class to be the "growth engine of our economy," Harris said she would cut taxes for middle class families and individuals, promising that more than 100 million Americans would get a middle-class tax break.
