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.

This was once the entrance to the Tower Subway, built in 1870 to provide a cable-car service under the Thames to Southwark. It was completed by J H Greathead in just 10 months at a fraction of the time and cost of the Brunel's earlier and ill-fated Thames Tunnel between Wapping and Rotherhithe which now forms part of the East London Underground line.
Work on the Tower Subway was hastened by the use of the 'Greathead Shield, which proved so successful that it was the forerunner of the methods used to build London's Tube system at the end of the nineteenth century.
Greathead, one of London's unsung heroes, was the engineer in charge of the King William Street to Stockwell line (now the City branch of the Northern Line), opened in 1890 as the world's first deep-level railway.
Sadly, Tower Subway was never very successful. The cable-cars were soon taken out of the tunnel, which was seven feet in diameter and more than 440 yards long, and it became a pedestrian passageway. In 1894 the subway was made redundant by the walkway incorporated into the new Tower Bridge. Today all the subway contains are water mains for the Thames Water Authority.
