Evan L. Schwab  served as law clerk to a US Supreme Court Justice that was nominated by which president?
William O. Douglas William Orville Douglas (October 16, 1898January 19, 1980) was an American jurist and politician who served as an Associate Justice of the Supreme Court of the United States. Nominated by President Franklin D. Roosevelt, Douglas was confirmed at the age of 40, one of the youngest justices appointed to the court. His term, lasting 36 years and 211 days (1939–75), is the longest in the history of the Supreme Court. In 1975 "Time" magazine called Douglas "the most doctrinaire and committed civil libertarian ever to sit on the court".
Merrick Garland Supreme Court nomination Following the February 2016 death of Associate Justice of the Supreme Court Antonin Scalia, President Barack Obama nominated Merrick Garland to fill Scalia's seat on the Supreme Court on March 16, 2016. At the time of his nomination, Garland was the Chief Judge of the United States Court of Appeals for the District of Columbia Circuit. Scalia's death led to an unusual situation in which a Democratic president had the opportunity to appoint a Supreme Court nominee while the Republicans controlled the United States Senate; before Scalia's death, such a situation last occurred when a Senate Republican majority confirmed Grover Cleveland's nomination of Rufus Wheeler Peckham in 1895. Conversely, in February 1988, during an election year, the Democratic-controlled Senate confirmed Anthony Kennedy, who was the Republican President Ronald Reagan's nominee for the Supreme Court, though Kennedy had been nominated in November 1987, and the vacancy had occurred in June 1987.
