Five House Democrats led by Alexandria Ocasio-Cortez of New York wrote to the US attorney general, Merrick Garland, to demand a federal investigation of the conservative supreme court justice Clarence Thomas, over his acceptance of undeclared gifts from billionaire rightwing donors.

“We write to urge the Department of Justice to launch an investigation into … Clarence Thomas for consistently failing to report significant gifts he received from Harlan Crow and other billionaires for nearly two decades in defiance of his duty under federal law,” the Democrats said.
