In a pitch to lawmakers, a leading liberal constitutional law scholar praised Supreme Court nominee Brett Kavanaugh as the “best candidate on the horizon,” and defended the prospective justice’s decision to avoid promising recusals in future cases involving President Donald Trump.

Yale Law professor Akhil Amar urged members of the Senate Judiciary Committee on Friday  to confirm his former law student, nearly two months after penning an op-ed that described Trump’s choice of Kavanaugh as “his classiest move.” Amar described Kavanaugh as someone whose qualifications cannot be knocked.
