There is David Ogden, the first deputy attorney general during the Obama administration years. There is Debo Adegbile, an unsuccessful assistant attorney general nominee in the Obama years who developed a corporate practice related to civil rights at Wilmer after joining the firm in late 2014. And there is Jamie Gorelick, another former deputy attorney general who represents Ivanka Trump and her husband, Jared Kushner, on their security clearance applications and federal ethics issues.
