Stefon Diggs' accuser, his former personal chef Mila Adams, took the stand Monday at his assault trial in Dedham, Massachusetts, facing tense cross-examination from the NFL star's defense attorney on the first day of trial. The former New England Patriots receiver is accused of attacking Adams last year. He's charged with felony strangulation or suffocation and misdemeanor assault and battery in the incident at his home on December 2. He has pleaded not guilty.
