Kamala Harris is skeptical of Biden's anti-trust enforcement

Corporate executives have chafed at Mr.

Biden’s regulatory agenda and his proposals to raise corporate tax rates and eliminate certain industry-specific tax breaks. Business leaders have also bristled at the actions of the Federal Trade Commission’s chair, Lina Khan, who has tried to crack down on corporate mergers.

As vice president, Ms. Harris has voiced support for regulating artificial intelligence. But she has expressed skepticism of Ms. Khan’s expansive view of antitrust powers, according to a donor who has spoken privately with the vice president.

Among the biggest differences between her financial policies and Mr. Biden’s in their 2020 presidential campaigns was that Ms. Harris proposed raising the corporate tax rate to 35 percent from 21 percent, while Mr. Biden’s proposed to raise it to 28 percent. The rate remains 21 percent, and Democrats will almost certainly seek to increase it next year when pieces of the Trump administration’s tax legislation expire.

Mark Chorazak, a partner at the law firm Skadden, Arps, Slate, Meagher & Flom and a Biden donor, said he did not view Ms.

Harris as “a continuation of every Biden policy.” But, he added, “I don’t see significant differences between what President Biden has fought for and what Vice President Harris will fight for.”
