Larry Gibbs, a former IRS Commissioner, commented on Charles Rettig's progress in his first year as IRS Commissioner. "It usually takes commissioners . . . almost a year just to know the agency enough to come up with what they want to do with the organization," Gibbs said. Rettig has managed to avoid getting caught up in the conflict over President Trump's tax returns, provided cover in part by Treasury Secretary Steven Mnuchin, Gibbs observed, "and I give [the secretary] high marks for that."
