Rivera, 77, who currently lives in Northeast Ohio, made the announcement on Twitter Wednesday saying he was “pondering” running for the retiring senator’s seat.
Rivera is a journalist, well known for his work on FOX News, who now hosts “Geraldo in Cleveland” on WTAM. He is also an attorney, author, political commentator and former television host.
He is reportedly a member of the Republican Party and has expressed several political opinions, including those about former President Donald Trump, on social media.
Rivera’s tweet comes after Portman, 65, announced last month that he will not seek reelection to the U.S. Senate in 2022.
The Republican from Cincinnati cited the “increasingly polarized” political climate as part of the reason for him stepping aside.
Portman assumed the Senate seat held by Republican George Voinovich in 2011. Portman previously served in the House of Representatives from 1993 to 2005 and was director of the Office of Management and Budget under President George W. Bush from 2006 to ’07.
