The National Association of Latino Elected and Appointed Officials (NALEO), the most well-known Hispanic political group, is calling on President Obama to appoint at least two Latinos to his second-term Cabinet.

Interior Secretary Ken Salazar on Wednesday became the second Latino Cabinet member to announce his departure in the last two weeks, along with now-former Labor secretary Hilda Solis. No other Hispanics serve in or have been appointed to Cabinet positions.

NALEO says  there should again be at least two Latinos in the Cabinet in Obama's second term.

"We call on the President to ensure that his administration is fully reflective of the diversity of this great nation by appointing at least two Latinos to Cabinet-level positions in his second term," the group said in a statement. "We appreciate the President’s continued commitment to strengthening our democracy by fully engaging Latino voices and talents, and look forward to continuing to work with him and his cabinet members in the coming years.”

Minority groups and women's rights groups have urged Obama to appoint more diverse Cabinet officials in recent weeks, after he nominated a slate of white men to replace some minorities and women who had departed or are departing after his in his first term.

But it's unusual for groups to say there should be a specific number of a given minority in the Cabinet.

During a Monday press conference, Obama acknowledged concerns about the lack of diversity in his Cabinet picks, but he urged patience as he fills out the rest of his team.

"I would just suggest that everybody kind of wait until they’ve seen all my appointment -- who is in the White House staff and who is in my cabinet -- before they rush to judgment," Obama said.
