Access name column elements from a Sharepoint list using REST

Question

I am using the following code to pull back items from a SharePoint List

        function getItems(url) {    
          return $.ajax({
          url: _spPageContextInfo.webAbsoluteUrl + url,
          type: "GET",
          headers: {
            "accept": "application/json;odata=verbose",
                   }
          });
        }

        getItems( "/_api/Web/Lists/GetByTitle('Reporting%   
         20Listing')/Items" ).done(function(data){
         data.d.results.forEach(function(item){  
         console.log( item.ID, item.Title, item.ApprovalName, 
         item.ApprovalDate );
            });
          });

This is working fine except item.ApprovalName is not returning any value.

Do I need to somehow reference which element of the ApprovalName array that I want? I've looked through several reference but don't see an example.

            $.ajax({

                async: false,
                success: function (data) {
                    if (data != null) {

                            console.log(data.d.results[i].Title);
                            for (var j = 0; j < data.d.results[i].MultiUsers.results.length; j++) {

                            }
                        }
                    }
                },
                eror: function (data) {
