Before joining Williams & Jensen, Hart worked in the PensionWelfare Benefits Program—now called the Employee Benefits SecurityAdministration. The agency is responsible for enforcing theEmployee Retirement Income Security Act of 1974, the act thatcreates minimum standards for private health and pension plans.

He also worked for the Pension Benefits Guaranty Corporation, agovernment agency in charge of protecting retirement income, andhas served on an ERISA task force at White House Office ofManagement and Budget.

Tax, benefits and retirement issues are slated for new scrutinyunder Trump’s Labor Department.

Under its current head, Thomas Perez, the department finalizedits fiduciary rule in April, which is aimed atminimizing conflicts of interest in the retirement-planningindustry.

Some observers expect the Trump administration to dismantle therule, although others disagree that he would make that apriority.

Hart during the Reagan administration served as the JusticeDepartment’s special assistant in charge of processing federaljudicial nominations.

Hart, with his breadth of clients and connections to majorcorporations, is a rainmaker for Williams & Jensen.

A 2014 study from the nonprofit Sunlight Foundation found he had raked in morethan $1 million in annual revenue for his firm, which has lobbyistsconnected to both major political parties, in 13 of the preceding15 years.

Trump has not revealed many specifics on the labor andemployment front. He has released a paid maternity-leave plan andspoken about the minimum wage. The expectation from labor andemployment lawyers was that Trump’s policies and personnelappointments in the labor field would lean conservative.

“[Trump appointees] would have very different views of labor andemployment issues than the people who have occupied those positionsin the last several years,” said Michael Lotito, a partner atLittler Mendelson in San Francisco who represents employers inlabor cases.

Donald Schroeder, a partner at Foley & Lardner’s Bostonoffice who represents employers, speculated that under Trump therewould be a return to the George W. Bush years in the form ofpro-business decisions from the Labor Department, the NationalLabor Relations Board and the Equal Employment OpportunityCommission.
