*1 Before: KOZINSKI , HAWKINS and BEA , Circuit Judges.

1. A court may consider prejudice to the government when determining whether to sever a joint trial. Fed. R. Crim. P. 14(a) (“If the joinder of . . . defendants . . . appears to prejudice a defendant or the government, the court may . *2 page 2 . . sever the defendants’ trials . . . .”). The court did not abuse its discretion in severing the trials so that defendants’ mutually inculpatory statements could be admitted while avoiding a Confrontation Clause problem. See Bruton v. United States, 391 U.S. 123, 126 (1968).

2. The special conditions of Arciero’s supervised release are not plainly

erroneous. See Fed. R. Crim. P. 52(b). When imposing the sentence, the court properly considered Arciero’s mental health history and drug and alcohol abuse. See United States v. Sales, 476 F.3d 732, 735–36 (9th Cir. 2007). Special condition number 2 is mandatory; it delegates to the probation office’s discretion only the details of mental health treatment. We have approved this practice. See United States v. Stephens, 424 F.3d 876, 880–84 (9th Cir. 2005). Special condition number 4 is neither vague nor overbroad, and it is reasonably related to rehabilitative goals. See United States v. Goddard, 537 F.3d 1087, 1089 (9th Cir. 2008) (citing 18 U.S.C. §§ 3583(d), 3553(a)).

AFFIRMED.
