Executives from Bezos' rocket company Blue Origin, including CEO Dave Limp, spoke with Donald Trump on Friday, The Associated Press reported. That was the same day the newspaper announced it would not endorse a presidential candidate for the first time in 36 years.
The New York Times reported that the decision was made by Bezos. The Washington Post Guild claimed on X that an endorsement of Kamala Harris had already been drafted.
The Post's publisher and CEO, William Lewis, said in a statement that reporting about Bezos' role involvement had been inaccurate.
"As Publisher, I do not believe in presidential endorsements. We are an independent newspaper and should support our readers' ability to make up their own minds," Lewis said.
"Donald Trump will see this as an invitation to further intimidate owner Jeff Bezos (and others)," Baron said on X.
Much of the focus in recent months has been on the former Amazon CEO's space entrepreneur rival, Elon Musk. Musk has campaigned extensively for Trump, who said in one campaign speech that "Elon promised" that "we will reach Mars before the end of my term."
Bezos, who has said nothing publicly about either candidate, has much at stake in the election.
Like all private space companies, Blue Origin relies heavily on federal contracts and is competing with SpaceX for government and military projects.
The rocket firm has a $3.4 billion contract with NASA to build a lunar lander for its Artemis V mission, which is due to carry people to the moon for the first time in decades.
Blue Origin was also selected in June as a preferred provider for Pentagon contracts worth $5.6 billion — the first time it's been given the green light to launch national security satellites.
The company is gearing up to launch its biggest rocket yet, the 320-foot New Glen, later this year.
That delay has seen SpaceX emerge as the clear leader in the private space race.
The Texas-based company launched its Falcon Heavy rocket nearly 100 times last year and is testing the even-larger Starship rocket that it plans to send to Mars in two years' time.
The SpaceX founder has been heavily involved in the campaign, donating tens of millions to a Trump campaign PAC and turning out for Trump in crucial battleground states.
Blue Origin did not respond to a request for comment from Business Insider.
