Earlier on the show, Issa accused Taylor of lying for his client.
"Well, her attorney has said things and been not correct, or disingenuous, or outright lied a number of times, and it's been shown by e-mails," Issa said on CNN. "Look, an attorney trying to get his client off the hook after flubbing the taking of the Fifth certainly will say and do a lot of things, but they're not held accountable."
Taylor also defended the decision to have Lerner plead the Fifth Amendment when she testified before Congress.
"There was no pretense that this would be a fair process," he said. "From the beginning, the Republican majority has screamed, without any evidence, about things that she did."
