Sen. Rob Portman (R-Ohio) will be the keynote speaker at Autumn Commencement, Ohio State announced Monday.

A native of Cincinnati, Portman didn’t attend Ohio State, but has represented the state of Ohio in Washington for almost two decades. He was first elected to the House of Representatives in 1993, and served until 2005. Portman was elected to the Senate in 2010 and was re-elected in 2016.

“Senator Portman has represented Ohio as an active, involved and committed citizen at the highest levels of government,” University President Michael Drake said in a press release. “He participates regularly in many of the most important conversations of our time and has a broad and lengthy record of service and legislative engagement.

“His extensive knowledge and experience will energize our students as they consider ways they might create their own mark on our broader world.”

After serving from 2005 to 2007 as the United States Trade Representative and then as Director of the Office of Management and Budget, Portman left government and worked at a law firm in Cincinnati.

In 2009, Portman announced his candidacy for Senate, and defeated Democrat Lee Fisher with 57 percent of the vote. Portman handily won re-election in 2016 with 58 percent of the vote, topping former Ohio Gov. Ted Strickland.

Last year, Timothy Gerber, a professor in the School of Music, was the keynote speaker at Autumn Commencement.

Ohio State having politicians speak at commencements isn’t a rare occurrence. Congresswoman Joyce Beatty, a Democrat who represents Ohio’s third district, spoke at Summer Commencement in August.

Former President Barack Obama addressed graduates at Spring Commencement in 2013.

Portman attended Dartmouth College for his undergraduate degree and received his law degree from the University of Michigan.

Autumn Commencement is set for Dec. 17 at the Schottenstein Center.
