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.

Tests have shown that the petals of the plant's tiny flowers can move at 22 feet per second when they open with an explosive force. The bunchberry dogwood - Cornus canadensis - grows in dense carpets in the vast spruce-fir forests of the North American taiga. The petals explode open to launch pollen an inch into the air, a study at Williams College in Willisamstown, Massachusetts, showed.
The pollen is ejected to 10 times the height of the small plant so that it can be carried away on the wind.
The scientists say inNature: "Bunchberry stamens are like miniature medieval trebuchets - specialised catapults that maximise throwing distance by having the payload [pollen in the anther] attached to the throwing arm [filament] by a hinge or flexible strap."
