On Dec. 3, Republican Sen. Johnny Isakson made a plea for bipartisanship in a farewell speech that took aim at the bitter division between the GOP and Democrats embroiled in a presidential impeachment process and nearing the start of a high-stakes election year.

Stating bluntly that "in America, we've got a problem," Isakson urged assembled lawmakers to work together and ignore the partisans eager to call them insults like Republican In Name Only - a term some conservatives are already using to criticize the Georgia businesswoman expected to take Isakson's place shortly.

"We may be called a liberal, we may be called a RINO, or we may be called whatever it is. Let's solve the problem and then see what happens," Isakson said from the Senate floor in Washington. "Most people who call people names and point fingers are people who don't have a solution themselves."

Recently, Isakson spoke with WSB’s Scott Slade to reflect on his time in the Senate and offer advice to those pursuing a career in politics.

Isakson, 74, announced in August that he would step down before the end of the year because Parkinson's disease and other medical issues were taking a toll on his health.
