From the Truman through Nixon administrations, justices were typically approved within one month. From the Reagan administration to the present, however, the process has taken much longer. Some believe this is because Congress sees justices as playing a more political role than in the past.[89] According to the Congressional Research Service, the average number of days from nomination to final Senate vote since 1975 is 67 days (2.2 months), while the median is 71 days (or 2.3 months).[90][91]
