Perhaps you missed this?
Cruz: “He flew back to D.C. Tuesday night, argued a complicated trademark case Wednesday morning, and returned immediately to Florida to continue helping us represent the president. Few, if any, other lawyers could have accomplished such a feat. Judge Roberts is a lawyers’ lawyer. And that matters immensely, especially for the U.S. Supreme Court.”

Cruz published a highly complimentary piece about Roberts in National Review with the obvious purpose of advocating for his confirmation.
Yes, I did miss that. Thanks for your correction. But it is still pertinent that Cruz recommended Luttig over Roberts.
