President Obama sat down with Steve Kroft on "60 Minutes" for his final network television appearance

In a preview of the interview, which airs Sunday, Obama said that his administration hasn't had a single major scandal during in his eight years of office.

"You didn’t change Washington," Kroft said to the president.

"I changed those things that were in my direct control," Obama said. "And I mean, look, I’m proud of the fact with two weeks to go, we are probably the first administration in modern history that hasn't had a major scandal in the White House."

"In that sense, we changed some things."

Obama said that he would have liked to accomplish more, but he was consistently obstructed by congressional Republicans.

He acknowledged that "shaping public opinion" is part of the job description of a president, and he failed to do that in some cases.

"There were big stretches, while governing, where even though we were doing the right thing, we weren’t able to mobilize public opinion firmly enough behind us to weaken the resolve of the Republicans to stop opposing us or to cooperate with us," Obama said.

"And there were times during my presidency where I lost the PR battle."
