--
Someone on Wednesday filed a document saying something in connection with a criminal case against President Donald Trump's former personal lawyer, Michael Cohen.
But who filed it and what it says are a mystery.
The document, which is sealed from public view, was "placed in vault" at U.S. District Court in Manhattan, according to a docket entry.
The filing came a week after Cohen, 52, was sentenced to three years in prison for his guilty pleas in cases brought separately by federal prosecutors in New York, and by the office of special counsel Robert Mueller.
