UPDATE: Congressman Rob Andrews Announces Resignation Amid Ethics Investigation

Congressman Rob Andrews will resign from office to pursue a position with Dilworth Paxson, the law firm confirmed Tuesday afternoon.

"I couldn't be more enthusiastic about joining Dilworth at this moment in its history," Andrews said in a statement released by the company. "I've enjoyed a long relationship with the Firm and count many of its members among my dear friends."

Andrews represented parts of Camden, Gloucester and Burlington counties during his time in office, which began in 1990.

He is the subject of an ethics investigation that centers around his use of $30,000 in campaign funds to finance a family trip, among other accusations.

He said the investigation had nothing to do with his decision to resign, according to nj.com. His term was set to expire at the end of the year.

"For nearly a quarter of a century, Congressman Rob Andrews has worked to improve educational opportunities for New Jersey students, to grow the economy responsibly, and to ensure a strong national defense,” New Jersey Democratic Committee Chairman John Currie said in a statement issued Tuesday afternoon. “Although I am confident in the prospects for Democrats to win his seat, he leaves a lasting legacy. No doubt, Congressman Andrews' presence in Washington, fighting on behalf of the people of the first congressional district, will be missed. I wish he and his family well as he begins a new endeavor."

“We're committed to securing talent with the kind of deep, broad based knowledge and problem solving expertise demonstrated by Congressman Andrews that allows us to enhance and expand the critical services and solutions we provide to our clients.” said Dilworth Paxson CEO Ajay Raju, who called Andrews a "welcome addition."

State Sen. President Steve Sweeney endorsed State Sen. Donald Norcross as Andrews’ replacement, according to nj.com.
