According to some official reports, Indiana University Law School professor Dawn Johnsen withdrew her nomination Friday to be assistant attorney general overseeing the Office of Legal Counsel.

ABC News has reported that she was "deeply honored that President Obama, the Attorney General and a strong majority of the U. S. Senate have demonstrated faith and confidence in my ability to lead the Office of Legal Counsel," Johnsen said in a statement.

She further added that the office "lays a critical role in upholding the rule of law and must provide advice unvarnished by politics or partisan ambition. That was my guiding principle when I had the privilege to lead OLC in a past administration. Restoring OLC to its best nonpartisan traditions was my primary objective for my anticipated service in this administration.

Johnsen said, "Unfortunately, my nomination has met with lengthy delays and political opposition that threaten that objective and prevent OLC from functioning at full strength."

Last year the Senate Judiciary Committee confirmed Johnsen along party lines, but Republicans blocked a full vote on her nomination.

Her "condemnations of counter-terrorism policies" indicated a "leftist agenda" that should exclude her from the position, said Sen. Jeff Sessions, R-Ala. (With Inputs from Agencies)
