Are statements made by a witness admitted for their truth under the confrontation clause?

¹⁹ If basis evidence is admitted for its truth for purposes of the confrontation clause, logic would seem to dictate these statements are also admitted for their truth under the hearsay rule. (See Hill, supra, 191 Cal.App.4th at p. 1132, 120 Cal.Rptr.3d 251.) However, People v. Gardeley (1996) 14 Cal.4th 605, 618619, 59 Cal.Rptr.2d 356, 927 P.2d 713, a pre-Crawford decision, holds that basis evidence is not admitted for its truth for purposes of the hearsay rule.
