Chief Justice nominee John Roberts (left) shares a light moment with Sen. Joe Biden during a break in his confirmation hearings, Sept. 14 , 2005. Earlier, Biden chided Roberts for offering "non-answers" to the Judiciary Committee.
The Senate Judiciary Committee on Wednesday began a second full day of testimony from Supreme Court nominee John Roberts.
During Wednesday's hearings, Sen. Tom Coburn (R-OK) raised concerns over the growing trend among some justices to cite foreign law to buttress their arguments. The issue has become a divisive one on the Supreme Court and among Republicans who object to the trend.
Right-to-die issues also came up several times. Coburn pressed Roberts to define the end of life. Sen. Joe Biden (D-DE) expressed frustration at Roberts' refusal to answer numerous questions on whether the chief justice nominee believes in a right to die and to make end-of-life decisions.
