Six Republican Senators have written a letter to President Obama questioning the president's continued reliance on "czars" to run key parts of the government.

"These positions raise serious issues of accountability, transparency, and oversight," the letter states. "The creation of "czars," particularly within the Executive Office of the President, circumvents the constitutionally established process of "advise and consent," greatly diminishes the ability of Congress to conduct oversight and hold officials accountable, and creates confusion about which officials are responsible for policy decisions."

The letters was signed by Sens. Susan M. Collins, Lamar Alexander, Christopher S. Bond, Mike Crapo, Pat Roberts and Robert F. Bennett.
