Earlier today it became apparent that President Bush's nominee to head immigration and customs enforcement is not entirely qualified for the position. Now the AP's Lara Jakes Jordan reports that one Democratic Senator is preparing to block the nomination -- but for separate reasons.

A Democratic senator threatened Tuesday to block approval of a Homeland Security Department nominee until he receives a secret FBI memo about terror suspect interrogations that he's been seeking for months.

The threat against Julie L. Myers, tapped to head the department's bureau of Immigration and Customs Enforcement, came amid lawmakers' concerns that she lacked the experience to head the federal government's second-largest investigative force.

Asked if he planned to use legislative delaying tactics against Myers nomination, Sen. Carl Levin, D-Mich., said: "Oh yeah. If we don't get the documents, sure."

At issue is a heavily edited May 2004 e-mail from FBI agents seeking guidance about questioning terror suspects held at Guantanamo Bay.

From our experience with Michael Brown at the head of FEMA, perhaps it's a good thing that Levin indends to block Myers' nomination -- even if it's for an unrelated reason.
