Walter Shaub doesn’t have time for fun these days.

The former head of the U.S. Office of Government Ethics under President Obama says he’s too busy trying to save the republic.

“Then I roll up my sleeves and go to work at Citizens for Responsibility and Ethics in Washington, where we’re putting up as strong a fight as we possibly can for this republic and for the ethical principles that were once the hallmark of its operations,” he said.

Shaub, once a little-known government bureaucrat, has risen in prominence since he resigned in protest from the Trump administration last summer.

Shortly before his departure and right after the 2016 election, a series of tweets were sent from the OGE’s official Twitter account, applauding then-President-elect Trump’s supposed decision to sell off his business empire’s assets. But Trump hadn’t decided to take such action.

“.@realDonaldTrump Brilliant! Divestiture is good for you, very good for America!” said one of the ethic office’s tweets.

Shaub, 47, was behind the messages. Now serving as a senior adviser at the watchdog group CREW, he’s also behind a slew of legal actions involving everything from the emoluments clause to spending and travel of government officials.

“My hobbies include screaming into the void and banging my head against a table,” Shaub joked yesterday during an interview.
