<p>Donald Trump has another endorsement from a former GOP presidential hopeful, this time from previous rival Ben Carson.</p><p>Carson said on Friday: &quot;There are two different Donald Trumps. There&#39;s the one you see on the stage, and there&#39;s the one who&#39;s very cerebral.&quot;</p><p>This comes after plenty of speculation over Trump possibly picking Carson as his running mate. And both have said they would consider being on the same ticket.</p><p>It was only about a week ago that Carson pulled out of the presidential race, but with some pivotal primaries coming up in Ohio and Florida, there&#39;s not much time left for Trump to gain the needed delegates.</p><p>Carson follows former GOP presidential hopeful Chris Christie, who endorsed Trump at the end of February.</p><p><i>This video includes clips from&nbsp;</i><i><a href="https://www.youtube.com/watch?v=W6B7qVkJMhg" target="_blank">ABC</a></i><i>,&nbsp;</i><i><a href="https://www.youtube.com/watch?v=7P5ak8N-3BA" target="_blank">CBS</a></i><i>&nbsp;and Fox News and images from Getty Images.</i></p>
