Members Who Have Served in the U.S. Congress for
30 Years or More
Summary
This report identifies the 234 Members of Congress who have served in
Congress for at least 30 years, as of July 7, 2008. Those 234 Members are only 2%
of the 11,828 individuals who have represented their states and congressional
districts in Congress since 1789.
Of the 234 Members with at least 30 years of congressional service, 137 have
spent all of their congressional careers in the House; 27 have spent all of their careers
in the Senate; and 70 have had combined service in the House and Senate. Among
Members of the 110th Congress, 16 Senators and 17 Representatives have served 30
years or more.
This report supercedes CRS Report RL30370, by Mildred Amer, Specialist in
American National Government. It will be updated as additional Members reach the

30-year mark, and at the beginning of each Congress.

Members Who Have Served in the U.S.
Congress for 30 Years or More
Introduction
As of July 7, 2008, a total of 234 persons have served for 30 years or more in1
the United States Congress as Representative or Senator. That number is only 2%
of the 11,828 men and women who have represented their states and congressional
districts since the First Congress convened on March 4, 1789. Of the 234 Members
serving 30 years or more, 137 served only in the House of Representatives; 27 served
only in the Senate; and 70 served in both chambers.
Over time, the number of Members serving 30 years or more has grown. Only
two Members with over 30 years of service were in Congress in the 18th century:
Nathaniel Macon began his service in 1791; Samuel Smith, in 1793. Seven served
entirely during the 19th century. By 1967 (90th Congress), a total of 100 Members had2th
served 30 years or more. As of July 7, 2008, (110 Congress) that number had risen
to 234. Among Members of the 110th Congress, 16 incumbent Senators and 17
incumbent Representatives have served 30 years or longer.
Table 1 lists Members who have served 30 years or longer in descending order
of the length of their congressional service, as measured in days.3 For each Member,
the table presents the Member’s party and state represented; dates of the Member’s
first and last day of service, by chamber; days of service in each chamber; and total
days of congressional service. Total service is also presented in years and fractions
of years.4

Record, Mar. 9, 1967, vol. 113, part 5, pp. 6191-6193.
3 Earlier editions of this report presented congressional service in terms of years, months,
and days. But the method was based on assumptions about the number of days per month
and was imprecise. This report avoids the imprecision associated with that method by
counting each Member’s days of congressional service, beginning on his or her first day of
service and ending on the last. In carrying out this approach, CRS used a computer
application that calculates the days elapsed from one date to another. The application knows
the number of days of each month, and it is designed to handle the intercalary day for leap
years. However, the number of elapsed days does not include the first day of service, so the
number of days served is equal to the number of elapsed days plus 1.
4 To report congressional service in terms of years and fractions of years, we divide the total
days served, which includes intercalary days for leap years, by the average number of days
in the Gregorian year (365.2425).

Calculation Method
Calculations of days of service varied according to the pattern of a Member’s
service. For example —
!Clarence A. Cannon of Missouri served in one continuous period from
3/4/1923 through 5/12/1964. The elapsed time from one date to the other
was 15,045, but because Representative Cannon served for each of the
elapsed days and on the first day, we add one day to the elapsed time for
a total of 15,046 days.
!Justin Morrill served in both the House and the Senate, continuously from
3/4/1855 to 3/3/1867 in the House (4,383 days) and from 3/4/1867 to
12/28/1898 in the Senate (11,623 days). Morrill’s total congressional
service was the sum of those two periods, 16,006 days.
!Henry Jackson of Washington also served continuously in both the House
and the Senate, but because of a statutory change there is an overlap of
one day in his official dates of service. Jackson served in the House from
1/3/1941 through 1/3/1953, but his first day in the Senate was also
on1/3/1953. If we simply added his House service (4,384 days) and his
Senate service (11,199 days), we would double-count 1/3/1953; so we add
the days of service in each chamber (15,583 days) and subtract one day
from that sum for Jackson’s total days of congressional service (15,582
days). Alternately, we could simply count the days from when his House
service started through the date of the day when his Senate service ended.
!Samuel Smith served in the House, then in the Senate, then again in the
House, and then once again in the Senate. His first period of service (in
the House) did not overlap with the second (in the Senate). There was a
break between his first period of Senate service and his second period of
House service, but there an overlapping day (12/17/1822) when he moved
finally from the House again to the Senate. Accordingly, we add the days
of each period of service and subtract one day from the sum for a total of

14,276 days of congressional service.

Table 1 draws the dates of congressional service from the Biographical5
Directory of the United States Congress, 1774-Present; the “Table of United States
Senators” in U.S. Congress, Senate, Senate Manual, S. Doc. 104-1; and various
editions of the Congressional Directory (Washington: GPO). When a date in the
Biographical Directory was unclear, CRS consulted other sources for clarification,
as shown in notes to Table 1.
