The US Supreme Court issued this press release yesterday:

Scott S. Harris, Legal Counsel at the Supreme Court of the United States, has been named the Court's new Clerk, effective September 1, 2013.   Harris will be the 20th Clerk of the Court.  He will replace William K. Suter, who will retire on August 31, 2013, after serving 22 years in that position.

Tony Mauro has this post at BLT.

The affable Harris has been counsel to the court for 11 years, a low-profile but important position at the court. As the high court's in-house counsel, he has been involved in a range of legal issues, including routine litigation and disputes over protests on court property. The legal counsel also provides support on "a variety of case-related issues," the news release stated.

For the nonlawyers among our readers, the clerk of the court is much higher-level position than the term "clerk" normally implies.  At SCOTUS, the clerk runs pretty much everything except the decision of the cases.
