Brett Kavanaugh, US President Donald Trump's pick for the Supreme Court, appears to check all the conservative boxes. On Monday evening, Trump nominated the 53-year-old judge to replace retiring Associate Justice Anthony Kennedy, 81, whom Kavanaugh once clerked for. Trump called Kavanaugh a "judge's judge, with a clear and effective writing style". In a major Second Amendment case, Kavanaugh dissented from a decision that upheld a ban on semiautomatic rifles. One contender was 6th Circuit Court of Appeals Judge Raymond Kethledge, 51, who also had once clerked for Kennedy.
