US aviation giant Boeing has told BBC News it is donating $1 million (£812,600) to an inauguration fund for President-elect Donald Trump.
Google also confirmed it has made a similar donation as the two companies join a growing list of major US companies contributing to the fund.
The list also includes oil producer Chevron and tech giants Meta, Amazon and Uber.
Trump’s inauguration, marking the start of his second term in the White House, is scheduled to take place on January 20.
“We are pleased to continue Boeing’s bipartisan tradition of supporting the U.S. Presidential Inaugural Committees,” Boeing said.
The company added that it has made similar donations to each of the last three presidential inauguration funds.
Boeing is struggling to recover from a safety and quality control crisis, as well as deal with losses caused by a strike last year.
The company is also building the next presidential jet, known as Air Force One. Both planes are expected to enter service next year.
During his first presidential term, Trump forced the plane maker to renegotiate its contract, deeming the initial agreement too costly.
Google became the latest major tech company to donate to the fund, following similar announcements from Meta and Amazon. He also announced that he would 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 Karan Bhatia, Google’s global head of government affairs and public policy.
Automakers Ford, General Motors and Toyota also donated $1 million each to the inaugural committee.
In the energy sector, Chevron confirmed it had donated to the fund, but declined to specify the amount.
“Chevron has a long tradition of celebrating democracy by supporting inaugural committees of both parties. We are proud to do so again this year,” said Bill Turene, Chevron’s head of global media relations.
