Sen. Jeff Sessions, R-Ala., renewed his call Thursday to postpone the confirmation hearing for federal appellate nominee Goodwin Liu, citing another discovery of information that Liu did not include in materials he sent to the Senate Judiciary Committee.

Sessions, the committee’s top Republican, said his staff has found nine additional speaking events that Liu did not list in response to a committee questionnaire. Liu has supplemented his original answers four times and apologized to senators for being incomplete, but Sessions said his staff this week found faculty colloquia and other previously undisclosed engagements.
