Your support helps us to tell the story
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.

Studies on graphene, a revolutionary material made of a single layer of carbon atoms, have revealed that electrons – subatomic particles that result in electricity – travel many times faster than in silicon, the basis of all modern computer chips.
The discovery suggests that it may be possible to create a new generation of super-fast mobile phones and computers based on graphene.
Professor Kostya Novoselov of Manchester University, who shared last year's Nobel prize in physics with colleague Andre Geim for their work on graphene, said research on layers of the material held in a vacuum has shown that electrons behave very differently when travelling through graphene.
"Electrons in graphene have huge mobility, they travel very fast. It's quite a big result in terms of the physics and it may have some implications in terms of potential applications," Professor Novoselov said.
Professor Geim and Professor Novolosev discovered graphene by using Scotch tape to peel away layers of carbon from a piece of graphite (pencil lead).
They were left with a two-dimensional film of carbon, one atom thick.
The carbon atoms are linked as a single molecule arranged in a hexagonal lattice.
Graphene possesses a number of unique properties, such as extremely high electron and thermal conductivities due to very high velocities of electrons and high quality of the crystals, in addition to mechanical strength.
