President Joe Biden is set to meet US business leaders including Jamie Dimon, chief executive of JPMorgan Chase, and Doug McMillon, chief executive of Walmart, as he seeks support from titans of corporate America for his $1.9tn stimulus plan.

The gathering in the Oval Office on Tuesday afternoon will mark Biden’s first with top business executives since his January 20 inauguration and is likely to set the initial tone for the relationship between the new administration and American companies.

Biden has embraced economic plans based on hefty government stimulus and infrastructure investment that is largely supported by American business given the economic downturn triggered by the pandemic.

However, business executives have been arguing that further spending needed to be tailored to the medical response and sectors most affected by the downturn, which could lead to disagreement over the size and details of the rescue plan.

Other aspects of Biden’s agenda, including higher taxation, an increased minimum wage and support for unionisation are also being watched warily by companies as they begin to wrestle with the new administration’s policies.

On the administration side, the meeting on Tuesday will include Janet Yellen, the US Treasury secretary, and Kamala Harris, the vice-president.

Tom Donohue, chief executive of the US Chamber of Commerce, Sonia Syngal, chief executive of Gap, and Marvin Ellison, chief of the home improvement retailer Lowe’s, were also expected to attend.

McMillon chairs the Business Roundtable, a lobbying group representing the top US blue-chip companies in the US capital.

Dimon has long been involved in policy debates in Washington, and is a board member and former chairman of the Business Roundtable. He has donated to both Democrats and Republicans in the past, and was at times considered a contender for a top job in the Biden administration.

“My heart is Democratic but my brain is kind of Republican,” Dimon told CNBC in 2019. Dimon’s presence at the meeting as the only representative of the financial services sector could set him up to be a leading conduit to Wall Street in a similar role to that performed by Stephen Schwarzman, the chief executive of Blackstone, during the Trump administration.

During the Trump administration, business largely embraced a big round of tax cuts and deregulation, but balked at the 45th president’s trade policies. Many executives also rejected his erratic policymaking style and leadership, and condemned his efforts to overturn the results of the 2020 presidential election, which culminated in the deadly assault on the US Capitol on January 6.

Biden is trying to rally business support for his economic stimulus after struggling to secure significant Republican support for his plan, forcing him to rely solely on members of his own Democratic party to clinch the passage of the package in a narrowly divided Congress.

However, White House officials have pointed to polls showing that their fiscal plan — which includes direct payments worth $1,400 to Americans earning up to $75,000 per year — is overwhelmingly popular among voters.
