Iowa’s two United States Senators will have new leadership roles in the Senate in 2019.

Republican Chuck Grassley has been a member of the United States Senate since January of 1981. It means when the calendar turns over to 2019, Grassley will be Republican with the longest tenure in the senate.

Because of that seniority, Grassley will become the Senate President Pro Tempore. He will be third in the line of succession to the presidency, behind the vice president and the speaker of the U.S. House.

Joni Ernst, Iowa’s other senator, today was elected vice chair of the Senate Republican Conference. She now ranks sixth on the leadership roster for Senate Republicans. She’s the first woman to be elected to Senate GOP leadership since 2010.
