Biden, Announcing A.I. Center, Highlights a Win of His and a Failing of Trump’s

President Biden on Wednesday announced the creation of an artificial intelligence data center in Wisconsin, highlighting one of his administration’s biggest economic accomplishments in a crucial battleground state — and pointing to a significant failure by his predecessor and 2024 challenger.

At the Gateway Technical College in Racine, Mr. Biden said the $3 billion project, which will be built by Microsoft, was an example of how he has delivered on promises that former President Donald J. Trump did not.

The Microsoft data center will be built on grounds where Mr. Trump, as president, announced in 2017 that Foxconn, the Taiwanese electronics manufacturer, would build a $10 billion factory for making LCD panels. Mr. Trump promised that it would be the “eighth wonder of the world,” and visited the site with elected officials and golden shovels. But the project never materialized as expected.

On Wednesday, Mr. Biden took direct aim at the failed promise. “Look what happened — they dug a hole with those golden shovels, and then they fell into it,” Mr. Biden told the crowd.

“During the previous administration, my predecessor made promises, which he broke more than kept, left a lot of people behind in communities like Racine,” Mr. Biden said. “On my watch, we make promises and we keep promises.”

In his fourth trip to Wisconsin this year, Mr. Biden continued his aggressive campaign to paint a contrast with Mr. Trump, the presumptive Republican nominee, who is in the fourth week of his criminal trial in connection with payments to a pornographic film star.
