Sen. Lamar Alexander, R-Tenn., said Tuesday his committee would act quickly to confirm President Trump's nomination of Marvin Kaplan to fill an open seat on the National Labor Relations Board, the main federal labor law enforcement agency.

The pick has drawn praise from business groups but little response from labor unions.

"Marvin Kaplan has the qualifications to be an effective member of the National Labor Relations Board. Once Mr. Kaplan's nomination paperwork is received, the Senate labor committee will move promptly to consider his nomination," said Alexander, chairman of the Senate Health, Education, Labor and Pensions Committee.

Kaplan is currently chief counsel of the Occupational Safety and Health Review Commission, an independent agency that hears appeals of citations and penalties by the Occupational Safety and Health Administration. He was previously a GOP staffer for the House Oversight and Government Reform Committee and House Education and the Workforce Committee.

The five-member board currently has two open seats. Trump elevated GOP board member Philip Miscimara to chairman, but the remaining two members are Democrats and board operates by simple majority.

Business groups and Republican lawmakers regularly complained the NLRB tilted pro-union under President Obama. They believe Kaplan would help to swing the pendulum back.

"We are hopeful the Senate will swiftly confirm Kaplan and President Trump will quickly fill the remaining seat so they can restore balance and reason to a labor board that has tipped the scales against the needs of employers and employees for far too long," said Robert Cresanti, president of the International Franchise Association.
