How to iterate list items from two list using where in powershell script

I have two list from where i want to collect common items. I am not able to make use of $caml in my script.

My script:

Add-PSSnapin Microsoft.SharePoint.PowerShell -erroraction SilentlyContinue
[System.reflection.Assembly]::LoadWithPartialName("Microsoft.SharePoint")

$web = Get-SPWeb "site name"

$list = $web.Lists["listname1"]

$DeleteBeforeDate = [Microsoft.SharePoint.Utilities.SPUtility]::CreateISO8601DateTimeFromSystemDateTime([DateTime]::Now.AddDays(0))

$caml='<Where>
    <And>
    <Eq><FieldRef Name="Status" /><Value Type="Text">Retired</Value></Eq>
    <Lt><FieldRef Name="Modified" /><Value IncludeTimeValue="TRUE"Type="DateTime">{0}</Value></Lt>
    </And>
    </Where> '-f $DeleteBeforeDate 

$query=new-object Microsoft.SharePoint.SPQuery

$query.Query=$caml

$items=$list.GetItems($query)

Write-host "Total Number of Retired Items in listname1="$items.Count

Write-host "Item List"

foreach ($item in $items)
{
    Write-host $($item.Name)

    Write-host $($item.ID)

    $CCLlist = $web.Lists["Listname2"]  

    $query1=new-object Microsoft.SharePoint.SPQuery 

    $items1=$CCLlist.GetItems($query1)

    Write-host "Total Number of Items in Listname2 ="$items1.Count

    Write-host "Item List" 

    $items1 | ForEach-Object {

                $m=$_['File Title:ID'].split(";")

        if($item.ID -eq $m[0])
                 {
           Write-host $($item.ID)

               Write-host $m[0]

               Write-host $_['Name']

          $Files = $CCLlist.Items | where {$item.ID -eq $m[0]}

                  foreach ($file in $Files)
                  {
             if($file.Name -eq $_['Name'])

                     {
            Write-Output "Deleting file $($file.Name)..."

                         $file.Delete() 
                     }
                  }

        }

    }

}
$items | % {$list.GetItemById($_.Id).Delete()}
$web.Dispose()
