Russia has helped amplify and spread false and misleading internet claims about recent hurricanes in the United States and the federal government’s response, part of a wider effort by the Kremlin to manipulate America’s political discourse before the presidential election, new research shows.

The content, spread by Russian state media and networks of social media accounts and websites, criticizes the federal response to Hurricanes Helene and Milton, exploiting legitimate concerns about the recovery effort in an attempt to paint American leaders as incompetent and corrupt, according to research from the Institute for Strategic Dialogue. The London-based organization tracks disinformation and online extremism.

In some cases, the claims about the storms include fake images created using artificial intelligence, such as a photo depicting scenes of devastating flooding at Disney World that never happened, researchers say.
