Powershell: Output for Record not working

Question

I have the following small scriptlet:

$JSON_obj = Get-Content -Path "C:\temp\importfile.json" | ConvertFrom-JSON

foreach ($Record_Set in $JSON_obj) {

 $Record_Set.Records

}

Running the script does not show anything on the console. If I manually type Record_Set.Records, the data will be shown. Any idea what could be the issue?

e.g. $Record_Set.Records-->
