Gov. Ned Lamont predicted on Monday that David Lehman, the controversial former Wall Street executive whose nomination has lingered for weeks amid pushback in the General Assembly, will be confirmed as the next commissioner for economic development. Speaking after an unrelated event at Quinnipiac University, Lamont said that Lehman is already focused on the task at hand, and is visiting towns and cities throughout the state, in an acting capacity, to lay the foundation for a revival of Connecticut’s business climate and recruitment. “We’re near the bottom of the barrel across 50 states going back a generation. I’ve asked a very different type of person to help lead our economic development efforts: David Lehman.” Lamont said Lehman has plans on how to attract more businesses and development so-called opportunity zones in cities. Lamont and Lehman have been pressing the nomination in the Senate, the only legislative body that needs to act on it. The governor has been calling senators, while Lehman has met privately with nearly all of the Senate’s 36 members. “I’m cautiously optimistic and hopeful,” Lehman said late Monday, declining to handicap which way any senators were leaning.
