WASHINGTON, May 28 (Reuters) - A U.S. appeals court on Tuesday set a fast-track schedule to consider the legal challenges to a new law requiring China-based ByteDance to divest TikTok's U.S. assets by Jan. 19 or face a ban.

The U.S. Court of Appeals for the District of Columbia ordered the case set for oral arguments in September after TikTok, ByteDance and a group of TikTok content creators joined with the Justice Department earlier this month in asking the court for a quick schedule. (Reporting by David Shepardson)
