A doctors’ group on Thursday filed a lawsuit claiming BART is infringing on their constitutional free speech rights by refusing to allow ads targeting technology executive Elon Musk in trains and stations.

The suit against the transit agency by the Physicians Committee for Responsible Medicine alleged BART is violating the 1st Amendment by refusing to let the nonprofit group display ads demanding Musk release videos of experiments on laboratory monkeys at his Neuralink “brain-machine interface” company.
