Former San Francisco Mayor Willie Brown is threatening legal action against Donald Trump for falsely claiming they nearly crashed in a helicopter together, during which Brown allegedly made negative comments about Vice President Kamala Harris. Brown vehemently denies Trump’s story, asserting that he has never been in a helicopter with Trump and has never spoken ill of Harris. Brown's attorney, Joe Cotchett, hinted that Trump’s actions are pushing Brown towards filing a lawsuit for slander and defamation. Former California state senator Nate Holden clarified that he was the one with Trump during the helicopter incident in 1990, suggesting Trump may have confused the two politicians. Brown insists legal action is necessary to stop Trump's lies, especially to protect Harris from any negative associations. Trump has threatened to sue The New York Times for its coverage of Brown's denials, further escalating the conflict.
