Last summer, former Connecticut U.S. Senator Joseph Lieberman, after finishing up 24 years in the Senate, took a job with the New York law firm of Kasowitz Benson Torres & Friedman. His niche is helping clients navigate the nuances of the federal government and its regulations.

Now it seems that he has some extra time on his hands. Last week, it was announced that the 71-year-old Lieberman, a former Connecticut attorney general, had taken a second position.

Lieberman is now chairman of the executive board of Victory Park Capital, a private equity firm in Manhattan. One of the firm’s partners and co-founders is Brendan Carroll, who worked as a staffer in Lieberman’s Senate office in the mid-1990s when Carroll was studying government at Georgetown University.

The men kept in touch after that, with Carroll taking a leave of absence from investment bank Robertson Stephens to assist in Lieberman’s 2000 vice presidential campaign.

Victory Park invests in companies across a range of industries, including oil and gas and airlines, and will benefit from Lieberman’s “wealth of experience,” Carroll said. Richard Levy, the managing partner of Victory Park Capital, said Lieberman’s “business acumen and deep policy background will be critical.”

As for Lieberman, he noted that he has long been interested in the business sector. “While in the U.S. Senate, I fought for policies that would allow small businesses to thrive,” Lieberman said in a prepared statement. “I look forward to a long-term partnership with Victory Park Capital that will position the firm for continued growth.”
