Justice Breyer participates in his last oral argument, colleagues offer 'deep appreciation'

The Supreme Court offered an affectionate tribute to Justice Stephen Breyer on Wednesday, after he participated in his last oral argument on that bench. 

Chief Justice John Roberts read a brief statement at the end of the more than two-hour argument session, his voice breaking when talking about his colleague’s memorable presence on the bench.

"This has been his arena for remarks profound and moving, questions challenging and insightful, and hypotheticals downright silly. This sitting alone has brought us radioactive muskrats and John the Tiger Man," said Roberts, who noted the other justices will later offer their personal thoughts on Breyer's retirement.
