Chuck Grassley Bio
Charles Ernest Grassley (born September 17, 1933) is an American politician and farmer who has represented Iowa in the United States Senate since 1981. A Republican and one of the longest-serving members of Congress in U.S. history, Grassley has served as president pro tempore of the Senate from 2019 to 2021 and again beginning in 2025. He became dean of the Senate in January 2023, making him the most senior member of the upper chamber.
Throughout his Senate career, Grassley has chaired the Finance Committee, the Judiciary Committee, the Aging Committee, and the Narcotics Control Caucus. Before joining the Senate, he served eight terms in the Iowa House of Representatives and three terms in the U.S. House of Representatives, establishing a long record of public service in his home state.
Early Life and Background
Charles Ernest Grassley was born on September 17, 1933, in New Hartford, Iowa, to Louis Arthur Grassley and Ruth (née Corwin) Grassley. He grew up in a rural farming family in Butler County, where his father Louis had purchased an 80-acre farm in 1926 after years of working as a farm hand in Hardin County. The family endured the hardships of the Great Depression, with Louis declining to expand the farm by an additional 80 acres because of tight finances.
Grassley attended New Hartford Community High School before enrolling at Iowa State Teachers College, now the University of Northern Iowa, where he earned both a Bachelor of Arts and a Master of Arts degree. He later pursued doctoral studies at the University of Iowa but did not complete his Ph.D. While in college, he held a job in Waterloo running an IBM machine, beginning a long pattern of combining factory work with public service.
Path to US Politics
After college, Grassley worked in Iowa factories, first as a sheet metal shearer at the Universal Hoist Company in Waterloo, and then on the assembly line at the Waterloo Register Company from 1961 until the plant closed in 1971. From 1967 to 1968, he taught at Charles City College. These experiences gave him a working-class perspective that would shape his political outlook.
Grassley entered electoral politics in 1958, winning a seat in the Iowa House of Representatives, where he would serve for eight terms. He was first elected to the U.S. House of Representatives in 1974, beginning a three-term tenure representing Iowa in Washington. In 1980, he successfully challenged Democratic incumbent John Culver for a seat in the United States Senate, launching what would become one of the longest Senate careers in American history.
Chuck Grassley Career
Early Career (1959–1980)
Grassley won his first race for the Iowa House of Representatives in 1958 and held that seat for sixteen years, from 1959 to 1975. During this period, he ran unopposed in every Republican primary election between 1958 and 1970, and was unopposed in his 1968 general election, the only race in his career in which he faced no major-party challenger.
He then moved to the U.S. House of Representatives in 1975, where he served three terms. In 1980, he defeated Democratic incumbent John Culver to win a seat in the United States Senate, beginning a career in the upper chamber that has continued to the present day.
Breakthrough (1981–1992)
Grassley’s first Senate victory came in 1980 against Democratic incumbent John Culver, marking the start of more than four decades in the upper chamber. He was reelected in 1986, defeating attorney John P. Roehrick and winning 98 of Iowa’s 99 counties, with Wapello County the only loss. In 1992, he won all 99 counties against Democratic state senator Jean Hall Lloyd-Jones, demonstrating his statewide strength.
Early in his Senate tenure, Grassley became known for his work on the Senate Judiciary Committee, voting against the creation of the Martin Luther King Jr. federal holiday in 1983 and later co-sponsoring legislation that gave King a posthumous award in 2004. He also participated in the confirmation debates over Supreme Court nominees Robert Bork, Douglas Ginsburg, and Anthony Kennedy during the Reagan administration.
Republican Era (1981–Present)
Grassley has continued to win Senate reelection by wide margins. In 1998, he defeated former state representative David Osterberg and again carried all 99 counties. He won a fourth term in 2004 against former state senator Arthur A. Small, a sixth term in 2010 against Democrat Roxanne Conlin and Libertarian John Heiderscheit, and a seventh term in 2016 against former Democratic lieutenant governor Patty Judge, winning more than 60 percent of the vote.
In September 2021, Grassley announced his candidacy for an eighth term and won the 2022 general election, defeating Democratic nominee Michael Franken. In November 2022, he filed for reelection for a ninth term in 2028, which would make him 95 at the time of the election and 101 at the conclusion of the term. On January 3, 2023, he became Dean of the United States Senate following the retirement of Patrick Leahy, and he has served as president pro tempore of the Senate since 2025, a position he previously held from 2019 to 2021.
Notable Events and Milestones
Grassley’s signature tradition is holding public meetings in each of Iowa’s 99 counties every year, a practice he has maintained since 1981, even after losing honorarium payments for them in 1994. The phrase “full Grassley” was coined to describe a presidential candidate visiting all 99 counties before the Iowa caucuses, a testament to his statewide presence. He is also the longest-serving Republican in congressional history and the sixth-longest-serving U.S. senator in history.

Chuck Grassley Family
Family Background and Farming Lineage
Grassley was raised in a farming family in Butler County, Iowa. His father, Louis Arthur Grassley, purchased an 80-acre farm in 1926 after years of renting land, while his mother was Ruth Grassley (née Corwin). Louis died in 1960, and Chuck began renting the family land. In 1965, he purchased 120 acres for about $36,000 to expand the farm, and after his mother Ruth died in 1974, he bought her 80 acres, bringing the total to 200 acres. He grew soybeans, oats, and alfalfa, and raised sheep, cattle, and hogs.
His son Robin began operating the farm at age 19 around 1980, and by 2000 the two worked 750 acres together, with Robin farming an additional 700 acres. As of 2018, Grassley farmed corn and soybeans with Robin and his grandson Pat. His grandson Pat Grassley has served in the Iowa House of Representatives since 2007 and was elected Speaker of the Iowa House in 2020.
Personal Life
Grassley married Barbara Ann Speicher on August 22, 1954, in Nashua at the Little Brown Church. The couple has five children and nine grandchildren. In May 1987, Barbara was diagnosed with breast cancer and had surgery in Waterloo to remove the tumors. The family has continued to be a central part of Grassley’s life throughout his decades in public office.
