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.

Spanish researchers believe a toothbrush which can take information from saliva samples and accurately detect changes could be used to alert people if they are at risk of cardiac disease.
It is hoped the brush could spot those at risk of heart failure and get them to take urgent action.
The team believes that if the system works, it will become a routine method of incorporating major health checks into daily life, helping people and doctors recognise changes in health and allowing adjustments in medication.
In the UK around 200,000 people a year will suffer a heart attack, with about 70,000 people dying from them.
Heart attacks, in which the supply of blood to the heart is suddenly blocked, become more common with age, and leave survivors with damaged heart muscle tissue, putting them at greater risk of another attack.
Cardiac disease, in which the heart struggles to pump blood properly due to its own blood supply issues, can raise sodium levels in saliva, which researchers at Hospital Ramón y Cajal in Madrid believe could provide an early warning of developing problems.
The team are also conducting tests to assess whether a smart toothbrush could monitor blood pressure and oxygen levels.
Cardiologist Alvaro Marco del Castillo who is collaborating with the research team on the design of the brush told The Times: “With a little information about their heart rate, pressure and some biological samples from saliva, it is possible to execute some minor corrections that should help the patient to be as healthy as possible.”
He added: “I am cooperating with a top-notch tech company which is trying to keep this new device as secret as possible while the engineering and designing phases are completed.”
The same research team helped Dr Marco del Castillo develop a “smart shirt” which helps monitor people’s vital signs. The team believes a technological revolution will put far more everyday health technology into the public realm.
