Alec Baldwin has sought to have the special prosecutor in his upcoming US hearing dismissed, saying that her involvement in the case is "unconstitutional".
Baldwin's lawyers argued that Andrea Reeb should be "disqualified" from the hearing, due to her elected position in the New Mexico House of Representatives.
The Hollywood actor is set to appear in court for the first time on February 24, and faces two charges of involuntary manslaughter over the fatal shooting of Rust cinematographer Halyna Hutchins.
