jquery ajax fails to parse valid json

jquery ajax fails to parse valid json

So I'm made a php script to output tweets in json and now I am trying to
parse with data with javascript. I've tested the data and it's valid json.
When I do the request in Example 2 it works fine. When I try to parse
using example 1 it fails saying Uncaught SyntaxError: Unexpected token N.
What is my problem?
Example 1
var request = $.ajax({
url: "http://website.com/twitter.php",
type: "GET",
data: {
twitter: 'google'
},
dataType: "json"
});
request.done(function(data) {
var resp = JSON.parse(data);
console.log(resp);
});
request.fail(function(jqXHR, textStatus) {
alert("Request failed: " + textStatus);
});
Example 2
var xhr = new XMLHttpRequest();
xhr.open("GET", "http://website.com/twitter.php?twitter=google", true);
xhr.onreadystatechange = function() {
if (xhr.readyState == 4) {
var resp = JSON.parse(xhr.responseText);
console.log(resp);
}
};
xhr.send();
