The Senate on Wednesday morning moved forward on President Trump’s pick of Marvin Kaplan to fill an open seat on the National Labor Relations Board, the main federal labor law enforcement agency.

Democrats and organized labor groups oppose the pick, who with Trump’s choice for the NLRB’s other open seat, William Emanuel, would give the board a Republican-led majority. The 50-48 cloture vote sets up a final Senate vote on Kaplan by the end of the week.
