(CNN) – As President Barack Obama finalizes his cabinet picks heading into his second term, some are pointing to a noted lack of diversity among the select group.

And Democratic Rep. Charlie Rangel says "it's embarrassing as hell." The congressman from New York pulled no punches Thursday when he chided the White House for not picking more women and minorities for the top level positions.

"The questions I've heard are fair," he said on MSNBC. "The record does speak for itself."

Obama's cabinet: Who's in, who's out?

Obama will nominate Jack Lew, his chief of staff, for Treasury Secretary on Thursday, and CNN has learned the likely contenders for his replacement at the White House are all men. This comes days after the president nominated former Sen. Chuck Hagel for Defense Secretary, Sen. John Kerry for Secretary of State, and John Brennan, chief homeland security and counterterrorism adviser, to lead the CIA.
