A day after being charged with attempted extortion, attorney Michael Avenatti continued to press his case against Nike Inc., taking to Twitter early Tuesday to publicize his claims that the sneaker giant made payments to amateur basketball players and their families.

Avenatti, who seized the spotlight last year as a lawyer for former adult-film actress Stormy Daniels, was arrested Monday and charged with allegedly attempting to extort more than $20 million from Nike, as well as bank fraud in another case. He was released on bond late Monday.
