US aviation company Boeing has told BBC News it is donating $1 million (£812,600) to President-elect Donald Trump’s inaugural fund.
Google and Microsoft have also confirmed they have made similar donations as the companies join a growing list of major US companies contributing to the fund.
The list also includes oil major Chevron and technology giants Meta, Amazon and Uber.
Trump’s inauguration, marking the start of his second term in the White House, is scheduled for January 20.
“We are pleased to continue Boeing’s bipartisan tradition of supporting US presidential inaugural committees,” said Boeing.
The company added that it has made similar donations to each of the past three presidential inauguration funds.
Boeing is working to recover from a safety and quality control crisis, as well as deal with damage from last year’s strike.
The company is also building the next presidential plane, called Air Force One. Both jets are expected to enter service early next year.
During his first term as president, Trump forced the planemaker to renegotiate its contract, calling the initial deal too expensive.
Google became the latest major tech firm to donate to the fund, following similar announcements by Meta and Amazon. It also said it will broadcast the event worldwide.
“Google is pleased to support the 2025 inauguration, with a live stream on YouTube and a direct link on our homepage,” said Kiran Bhatia, Google’s global head of government affairs and public policy.
Car companies Ford, General Motors and Toyota have also donated $1 million to the inaugural committee.
In the energy industry, Chevron confirmed it had contributed to the fund but declined to say how much.
“Chevron has a long tradition of celebrating democracy by supporting inaugural committees of both parties. We’re proud to do it again this year,” said Bill Turrin, Chevron’s manager of global media relations.
