Matheson recently retired from Congress after seven terms and most recently served as a chief deputy whip for House Democrats.
“During his time on the Hill, Jim was known as a legislator who was able to work with colleagues on both sides of the aisle to get things done,” former Sen. John Breaux (D-La.), co-chair of Squire Patton Boggs’ lobby shop, said in a statement. “Jim is an extremely well-respected individual who has a reputation for working hard and getting results for those he represents. We’re very pleased he’ll be joining us.”
"The high level of talent at Squire Patton Boggs gives the firm the capability to successfully address the most complex public policy issues," said Matheson. "I am excited to join this remarkable team of professionals."
Matheson faces a "cooling off" period before he can lobby Congress.
