As mentioned before, certain Republicans are blocking Obama's nominee to be the new ambassador to El Salvador. Last December, Obama nominated Washington, D.C. lawyer Mari Del Carmen Aponte to the position. She was questioned in testimony before the Senate Foreign Relations Committee in March about allegations from the mid 1990's about her relationship with a Cuban diplomat allegedly tied to that nation's intelligence services.
According to the Miami Herald:
Her Obama administration nomination to the El Salvador job was approved by the Senate Foreign Relations committee April 27, with 10 Democrats endorsing her -- including Cuban-American Sen. Bob Menendez of New Jersey -- and eight Republicans voting no.
But the Republicans will put a hold on her nomination when it comes up in the full Senate, meaning it will need 60 votes for confirmation unless they lift the hold, said congressional staffers who asked for anonymity because they were not authorized to speak on the topic.
A similar report about the plan's to continue to block the nomination appeared in The Cable.
