President Biden told companies vying with one another for a sharply constrained global supply of semiconductors that he has bipartisan support for government funding to address a shortage that has idled automakers worldwide.

During a White House meeting with more than a dozen chief executives on Monday, Biden read from a letter from 23 senators and 42 House members backing his proposal for $50 billion for semiconductor manufacturing and research.

“Both sides of the aisle are strongly supportive of what we’re proposing and where I think we can really get things done for the American people,” Biden said. “Now let me quote from the letter. It says, ‘The Chinese Communist Party … plans to reorient and dominate the semiconductor supply chain.’”

Chief executives including General Motors Co. CEO Mary Barra, Ford Motor Co.‘s James D. Farley, Jr. and Sundar Pichai, CEO of Alphabet and Google, participated in the virtual summit.

White House Press Secretary Jen Psaki said the meeting showed the administration is serious about addressing supply-chain constraints and softening the blow for affected companies and workers.

National Economic Council Director Brian Deese and National Security Advisor Jake Sullivan hosted the meeting, with Commerce Secretary Gina Raimondo also participating. Companies invited to join included Dell Technologies Inc., Intel Corp., Medtronic, Northrop Grumman Corp., HP Inc., Cummins Inc., Micron Technology Inc., Taiwan Semiconductor Manufacturing Co., AT&T Inc. and Samsung Electronics Co., as well as GM, Ford and Alphabet Inc.

Intel CEO Pat Gelsinger said in an interview after the meeting that the White House and Congress are working aggressively to support the semiconductor industry with more domestic manufacturing, research and development as well as efforts to build the workforce.

The administration intended to highlight elements of the president’s proposed $2.25-trillion infrastructure-focused plan that it believes would improve supply-chain resilience, a White House official said. The agenda also included discussions about the auto industry’s transition to clean energy, job creation and ensuring U.S. economic competitiveness, the official added.

Many of the lawmakers supporting additional funding for semiconductors want to see the measure in a stand-alone competitiveness bill aimed at China, not as part of Biden’s infrastructure package, as it is now. The China bill has some bipartisan support and could have a quicker path through Congress.

But exactly how to spend and allocate the semiconductor funding is a source of debate among automakers and other buyers of chips, as well as the semiconductor companies themselves.

Carmakers are pushing for a portion of the money to be reserved for vehicle-grade chips, warning of a potential 1.3-million-chip shortfall in car and light-duty truck production in the U.S. this year if their industry isn’t given priority.

Yet makers of other electronic devices affected by the chip shortage, such as computers and mobile phones, have taken issue with the carmakers’ demands, worried that their industries will suffer. The debate was also a factor in the White House meeting.

“There were many, many voices saying, ‘Hey, we can’t just start carving things up for particular industries. We need a solution that works in the medium and long term and that are sensitive to some of the unique challenges of the immediate term,’ ” Gelsinger said in the interview. “I think we’re working pretty well through that process right now. Nobody will be entirely happy but we’re heading in a good direction.”

The White House has not taken a public position on the issue but has indicated privately to semiconductor industry leaders that it would not support special treatment for one industry, according to people familiar with the matter.

Matt Blunt, president of the American Automotive Policy Council, which lobbies for Ford, General Motors and Stellantis (formerly Fiat Chrysler Automobiles), expressed optimism that the Biden administration would at least consider his industry’s arguments.

He said the White House has not endorsed any specific plans for setting aside money for carmakers but administration officials “understand why the proposal was made.”

To avoid future chip shortages, Blunt’s group proposed that at least 25% of any federal support for the construction of semiconductor factories must go to U.S. facilities that commit to allocating at least 25% of their capacity to automotive-grade chips.

John Neuffer, president and chief executive of the Semiconductor Industry Assn., said the industry understands “the difficulty the auto sector is feeling right now, and chipmakers are working hard to ramp up production to meet demand in the short term.”

For the long term, he said, the industry needs a boost in domestic production and innovation across the board “so all sectors of our economy have access to the chips they need, and that requires swiftly enacting federal investments in semiconductor manufacturing and research.”
