WASHINGTON (AP) For more than a half-century, the voice emerging from the U.S. Chamber of Commerces monolithic, Beaux Arts-styled building near the White House was predictable: It was the embodiment of American business and, more specifically, a shared set of interests with the Republican Party .

The partys bond with corporate America, however, is fraying.

Fissures have burst open over the GOPs embrace of conspiracy theories and rejection of mainstream climate science, as well as its dismissal of the 2020 election outcome. The most recent flashpoint was in Georgia, where a new Republican-backed law restricting voting rights drew harsh criticism from Delta Air Lines and Coca-Cola, whose headquarters are in the state, and resulted in Major League Baseball pulling the 2021 All-Star Game from Atlanta.

Republicans were furious. Senate Minority Leader Mitch McConnell of Kentucky warned that their actions were quite stupid, alienating a lot of Republican fans. GOP strategists argued that they no longer needed corporate Americas money to win elections as they try to rebrand as a party of blue-collar workers.

That extends an opportunity to President Joe Biden and congressional Democrats to find an ally in an unlikely place when the party has unified control of the federal government for the first time in a decade. Biden is pushing an ambitious $2.3 trillion infrastructure package that includes corporate tax increases which the White House is characterizing to CEOs as upfront investments that will ultimately make companies more profitable.

Its important for making the country more competitive, said Cedric Richmond, the White Houses director of public engagement. We think the plan is so important to the country that we are advocating and singing its praises to all businesses.

Commerce Secretary Gina Raimondo estimates she has talked to more than 50 business leaders about the plan, including a round of Easter weekend phone calls. She is encouraging companies to focus on the entire package instead of the tax increases.

You cant look at one piece of it and say that one number makes you walk away, she said. They say, Thats fair. Let me think about it. Thats how they run their businesses.
