How to do multiple caml query?

Hi All,

I would like to have two caml query in below code:

var siteUrl = '/sites/MySiteCollection';

function retrieveListItems() {

    var clientContext = new SP.ClientContext(siteUrl);
    var oList = clientContext.get_web().get_lists().getByTitle('Announcements');
        
    var camlQuery = new SP.CamlQuery();
    camlQuery.set_viewXml('<View><Query><Where><And><Eq><FieldRef Name="Project_x0020_Code" /><Value Type="Lookup">NGI-P1</Value></Eq><Eq><FieldRef Name="Project_x0020_Issue_x0020_Status" /><Value Type="Choice">Issue</Value></Eq></And></Where></Query></View>');
    this.collListItem = oList.getItems(camlQuery);
    clientContext.load(collListItem);
    clientContext.executeQueryAsync(Function.createDelegate(this, this.onQuerySucceeded), Function.createDelegate(this, this.onQueryFailed));        
}

function onQuerySucceeded(sender, args) {

    var listItemInfo = '';

    var listItemEnumerator = collListItem.getEnumerator();
        
    while (listItemEnumerator.moveNext()) {
        var oListItem = listItemEnumerator.get_current();
        listItemInfo += '\nID: ' + oListItem.get_id() + 
            '\nTitle: ' + oListItem.get_item('Title') + 
            '\nBody: ' + oListItem.get_item('Body');
    }

    alert(listItemInfo.toString());
}

function onQueryFailed(sender, args) {

    alert('Request failed. ' + args.get_message() + '\n' + args.get_stackTrace());
}

In the same code want to add another caml like below. The difference between two query is filter by 'issue' and 'risk'. How to achieve this?

camlQuery.set_viewXml('<View><Query><Where><And><Eq><FieldRef Name="Project_x0020_Code" /><Value Type="Lookup">NGI-P1</Value></Eq>
<Eq><FieldRef Name="Project_x0020_Issue_x0020_Status" /><Value Type="Choice">Risk</Value></Eq></And></Where></Query></View>');
