        Map<Id,ProcessInstance> xyz = new Map<Id,ProcessInstance>();

        Map<Id,ProcessInstanceStep> abc = new Map<Id,ProcessInstanceStep>();

        for(ProcessInstance pi : [SELECT Id,Status,TargetObjectId FROM ProcessInstance WHERE TargetObjectId =: newmap<object>.keySet() ORDER BY CreatedDate DESC]){

 system.debug('anyname'+abc.get(p.Id).Comments);

 <field that u want the comments> = abc.get(p.Id).Comments;
