Chuck Grassley

**Charles Ernest "Chuck" Grassley** (born September 17, 1933) is the senior U.S. Senator from Iowa. He is currently the president pro tempore of the Senate and also had this position from 2019 until 2021.  He has been Senator since 1981. He was also in the United States House of Representatives from 1975 to 1981. Before that he was in the Iowa state legislature from 1959 to 1974.

## Later Senate career

In January 2019, Grassley became the most senior Republican serving in the United States Senate due to the retirement of Orrin Hatch and the resignation of Thad Cochran. After the Republicans kept control of the Senate in the 2018 elections, Grassley became the 91st Senate President pro tempore.

In January 2021, when Republicans lost control of the U.S. Senate, Patrick Leahy became President pro tempore while Grassley became _President pro tempore emeritus_. With over 40 years in the U.S. Senate, Grassley is the longest-serving Republican senator in American history. He became President pro tempore again in 2025.

In January 2023, with Patrick Leahy's retirement, Grassley became the Dean of the United States Senate.

## Personal life

Grassley is also known for his widely reported "feud" with the History channel. He has accused the network multiples times of having little actual history programming.

Grassley's net worth was $7,550,075 as of 2018.

On November 17, 2020, Grassley announced that he had tested positive for COVID-19.
