WASHINGTON — Democrat Harry Hoglander has been nominated by President Obama for a fourth three-year term — this one to expire in June 2014 — on the three-member National Mediation Board, which administers the Railway Labor Act.

Earlier this year, Obama nominated Republican Thomas M. Beck to succeeded Republican Elizabeth Dougherty for a term expiring in June 2013.

It is expected the two nominations will move forward in tandem for Senate confirmation.

Democrat Linda Puchela is the third member of the NMB, serving a term that expires in June 2012.

Prior to Senate confirmation to his first term in 2002, Hoglander was a legislative aide to Rep. John Tierney (D-Mass.), where he focused on aviation and rail issues. Previously, Hoglander was a Trans World Airlines pilot and executive vice president of the Air Line Pilots Association. Educated as an attorney, Hoglander was a U.S. Air Force fighter pilot and retired with the rank of lieutenant colonel.

Beck, an attorney, has been serving as a Senate-confirmed member of the Federal Labor Relations Authority, which administers labor-management relations for non-Postal Service federal employees. Previously, Beck practiced labor law in the private sector and was a part-time professor of public policy at George Mason University in Fairfax, Va.
