Back in September, we wrote about Sen. Jeff Sessions’ discovery of what he called the “ACLU chromosome”—according to the senator, a common genetic defect that disqualifies bearers from the federal judiciary.

Well, Dr. Sessions is back at it. TPM has this video of Sessions ranting yesterday about the supposed prevalence of the “ACLU chromosome” in President Obama’s judicial nominees:

As Sen. Mark Udall later pointed out on the Senate floor, it’s unlikely that Sen. Sessions would have a similar reaction to a “Federalist Society chromosome”. While a few of President Obama’s nominees have had a history working with the ACLU—for instance, Edward Chen of California who worked to prevent discrimination against Asian Americans—President Bush made a point of packing the courts with judges who belonged to the far-right Federalist Society.

It’s absurd arguments like Sessions’ that are keeping qualified, well-respected nominees like Chen from even receiving an up or down vote in the Senate. While reports say that the Senate GOP has finally agreed to vote on 19 judicial nominees who they have been stalling despite little or no opposition to their confirmations, four nominees, including Chen, will be left out to dry without even a vote.

And, for the record, the ACLU had this to say about Sessions’ rant:

"Senator Sessions’ reference to ‘ACLU DNA’ in President Obama’s judicial nominees should be greeted as a welcome discovery by all Americans, regardless of party. For 90 years, the ACLU has defended the rights enshrined in the Constitution for everyone, regardless of their political beliefs. While not everyone agrees with us on every issue, Americans have come to rely on the ACLU for its unyielding dedication to principle."

"There is a long record of highly respected ACLU-affiliated lawyers who have been appointed to the federal bench, including luminaries such as Supreme Court Justices Thurgood Marshall, Felix Frankfurter, Arthur Goldberg and Ruth Bader Ginsburg. All have demonstrated their dedication to the Bill of Rights in important decisions supporting freedom of speech, the right to due process and gender and racial equality. There are also dozens of highly regarded district court and appellate court judges who have served or serve now on federal benches throughout the nation. Their ACLU background has helped them bring to the judicial system a steadfast commitment to constitutional values and an understanding of the critical role that the judiciary plays in safeguarding them."

"If you ask us, ACLU chromosomes make for a pretty remarkable gene pool," she added.
