Top figures in the pro-Trump media are claiming Supreme Court Justice Ruth Bader Ginsburg is hiding a secret illness or is even dead, elevating a bizarre new claim from the fringe QAnon conspiracy theory.

On Thursday, former White House adviser Sebastian Gorka suggested on Twitter that the Ginsburg, 85, who has cancelled public appearances since undergoing surgery to remove cancerous lung growths in late December, might be hiding a medical condition. But, Gorka tweeted, all would have to be revealed if Ginsburg appeared at the State of the Union address on Feb. 5.

“Still no sign,” Gorka wrote. “6 days left until Ruth Bader Ginsberg has to make her official appearance at @realDonaldTrump’s State of the Union.”
