Obama's nominee for Transportation Security Adm. withdrew his name from consideration.

(CNN) - The Obama administration's nominee to head the Transportation Security Administration withdrew his name from consideration Wednesday, according to the White House.

Erroll Southers, assistant chief for homeland security and intelligence at Los Angeles World Airports Police Department, was nominated for the post by President Barack Obama in early September.

He came under fire from the GOP for testimony before Congress in which Senate Republicans claim he gave incomplete information about accessing a federal database for personal reasons. The move led to a censure from the FBI.

Sen. Jim DeMint, R-South Carolina, also spearheaded GOP objections to Southers based on concerns over the TSA becoming unionized.

Specifically, DeMint and other Republicans have expressed concern that collective bargaining - a union tactic allowing workers to organize together and negotiate on issues such as hoursand wages - would be allowed if Southers takes over. (CONTINUES HERE)
