Los Angeles ( CNN ) -- Chris Brown must stay locked up in the Los Angeles County jail for at least another week while his lawyer negotiates with the prosecutor about his probation violation , a judge said Thursday . Brown attended a hearing Thursday wearing an orange jail suit , just hours after a cross-country trip from Washington to Los Angeles on the federal government 's inmate transport system , informally known as `` Con Air . '' `` He 's doing remarkably well under the circumstances , '' Brown lawyer Mark Geragos told CNN . `` It 's a challenging situation to be in . '' Geragos and Assistant District Attorney Mary Murray agreed to hold talks over the next week concerning Brown possibly admitting that he violated his probation . If that happens , it will be announced at a hearing next Friday . Otherwise , the judge will set a date for a trial on his probation revocation . `` I 'm hoping we get it resolved and we get it resolved quickly , '' Geragos said after the hearing . Geragos said he would also file a motion to have Brown released from jail , which would be considered at the May 9 hearing . Brown , who turns 25 next Monday , spent most of the past week traveling back to Los Angeles following a delay in the start of his trial on a misdemeanor assault charge in Washington . U.S . Marshals , who took Brown from the Los Angeles County jail for extradition to Washington four weeks ago , handed him back to Los Angeles Sheriff 's deputies just hours before Thursday 's hearing , according to Deputy U.S . Marshal Laura Vegas . Brown 's probation for the 2009 beating of ex-girlfriend Rihanna Fenty was revoked after his Washington arrest . He 's spent the past six weeks in custody and previous five months in court-ordered rehab . The prosecutor said last week that she would `` strenuously object '' to Brown being released because it appears likely Brown will be found guilty of the assault charge in Washington . Assistant District Attorney Mary Murray argued the only change since Brown was jailed in March is that his case has `` gotten worse . '' The Washington judge who found his bodyguard guilty in the assault case also concluded that Brown was `` the initial aggressor '' in the incident , Murray said . A Los Angeles judge refused a request last week to free the singer from custody so he could make his own way back from Washington . He and bodyguard Christopher Hollosy were arrested on assault charges in Washington for allegedly beating a man who tried to take a photo of Brown last October . The arrest led to a revocation of Brown 's probation , but he was allowed to enter a rehab program instead of going to jail . He was ordered to jail last month when he was kicked out of the rehab program for rules violations . Planes , chains and automobiles : Chris Brown 's miserable trip to trial . `` I think it 's a little over the top to have him in custody on this misdemeanor when everybody saw the bodyguard 's trial and which was nothing more than a bloody nose , '' Brown lawyer Mark Geragos told reporters in Washington last week . `` And you have got the bodyguard who was convicted and who readily admitted he was the one who did the punching.Â So all of this is much ado about nothing . '' Chris Brown 's freedom at stake with 2 cases . The delay in Brown 's Washington trial came after prosecutors refused to grant immunity to Hollosy so he could testify without jeopardizing his own case . On Monday , Hollosy was found guilty of assaulting a man on a Washington sidewalk before Brown 's trial was to begin in the case . The prosecutors cited Hollosy 's refusal to talk to them about his testimony as a major reason for the decision not to grant immunity . Their motion also said they suspected he might lie in his testimony to help Brown .
