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.

Researchers found that both average ground and sea surface temperatures around the world could be abnormally high between 2018 and 2022.
The biggest factor driving the forecast was an increased likelihood of "extreme warm events".
The research was carried out before the summer heatwaves that sent temperatures in the UK and other parts of the world soaring this year.
But the unusually hot weather was correctly predicted by the scientists, who said 2018 had a "high probability of having a warm anomaly" relative to the general effects of global warming.
Their paper, reported in the journal Nature Communications, was received for publication in January.
The new technique, called Procast (Probabilistic forecast), seeks to rationalise the inherently chaotic behaviour of systems such as the Earth's climate.
It involves gathering information from previous changes in a system's state to calculate the probabilistic chances of transitions to future new states.
A retrospective test of the method accurately predicted the global warming pause, or "hiatus", between 1998 and 2013.
The scientists, led by Dr Florian Sevellec, from the University of Brest in France, wrote: "For 2018-2022, the probabilistic forecast indicates a warmer than normal period, with respect to the forced trend (of global warming).
"This will temporarily reinforce the long-term global warming trend.
"The coming warm period is associated with an increased likelihood of intense to extreme temperatures."
Warm events affecting sea surface temperatures could increase the activity of tropical storms, said the scientists.
