President Obama will nominate two longtime labor lawyers to the National Labor Relations Board, withdrawing two contested appointees as part of a deal struck to avert a showdown over the filibuster in the Senate.

The new nominees are Kent Hirozawa, who currently serves as chief counsel to the National Labor Relations Board chairman, and Nancy Schiffer, the general counsel at the AFL-CIO. 

Obama appointed Richard F. Griffin Jr. and Sharon Block to the NLRB during a 2011 congressional recess after they were blocked by Republicans in the Senate. An appeals court later ruled that those appointments were unconstitutional. The Supreme Court will weigh in on the issue next year.

In exchange for the new nominees and the preservation of Senate rules, Republicans have promised a speedy confirmation process that would make the board fully operational by next month.
