From reproductive rights to climate change to Big Tech, The Independent is on the ground when the story is developing. Whether it's investigating the financials of Elon Musk's pro-Trump PAC or producing our latest documentary, 'The A Word', which shines a light on the American women fighting for reproductive rights, we know how important it is to parse out the facts from the messaging.
At such a critical moment in US history, we need reporters on the ground. Your donation allows us to keep sending journalists to speak to both sides of the story.
The Independent is trusted by Americans across the entire political spectrum. And unlike many other quality news outlets, we choose not to lock Americans out of our reporting and analysis with paywalls. We believe quality journalism should be available to everyone, paid for by those who can afford it.

The Energy Security Secretary said collecting solar power in space and beaming it wirelessly to Earth could generate round-the-clock electricity in all weathers.
Speaking at London Tech Week, he said: “With the climate clock ticking, innovation has never been so important.
“Half of the emissions reductions required to reach net zero by 2050 will have to come from technologies which are not yet totally commercially available.”
The technology for generating solar power in space for use on Earth is still being developed, but scientists at the California Institute of Technology announced earlier this month that they had managed to beam “detectable power” to Earth through microwaves.
Mr Shapps said ultra-lightweight solar cells which could be put into space more efficiently have also been developed.
“Space-based solar energy farms could deliver clean energy day and night far more efficiently and, of course, in all weathers,” he said.
He suggested the technology could generate 10 gigawatts of power by 2050 – enough for three-quarters of Britain’s homes – with the industry having the potential to create 143,000 jobs.
Eight projects have been awarded a share of the £1 billion Net Zero Innovation Portfolio fund.
Beneficiaries include the University of Cambridge, Queen Mary University of London, Port Talbot’s MicroLink Devices, the University of Bristol, Didcot’s Satellite Applications Catapult, Imperial College, and EDF Energy.
Dr Mamatha Maheshwarappa, payload systems lead at the UK Space Agency, said: “Space technology and solar energy have a long history – the need to power satellites was a key driver in increasing the efficiency of solar panels which generate electricity for homes and businesses today.
“There is significant potential for the space and energy sectors to work together to support the development of space-based solar power, and the UK Space Agency has contributed £1 million to these innovative projects to help take this revolutionary concept to the next level.”
