Prosecutors are investigating a hush money payment of $130,000 (around €122,000) that Trump's private attorney at the time, Michael Cohen, made to porn actress Stormy Daniels shortly before the 2016 presidential election. Daniels, whose real name is Stephanie Clifford, says she had sex with Trump years before the election, which Trump denies.

The payment was apparently intended to prevent Clifford from going public, which could have harmed Trump during the election campaign. The cash flows may have violated campaign finance laws.

Should Trump be indicted, it would be the first time a former US President has been indicted. The 76-year-old Republican announced a new presidential bid last November and wants to retake the White House in the 2024 elections.
