Rumor has it Sen. Pat Toomey (R-Pa.) is having second thoughts on his own judicial nominee moving forward.

The senator had long supported Colombian-born U.S. District Judge Luis Felipe Restrepo, who last year was nominated by President Barack Obama to serve on the United States Court of Appeals for the Third Circuit, which includes parts of Pennsylvania, New Jersey, and Delaware.

But now it seems Toomey is taking too much time or is withholding the so-called "blue slip" of the Judiciary Committee, the one that allows the nomination to move forward.

When questioned by The Huffington Post about this delay, Toomey gave an unclear answer.

"No, I'm not. Well, let me explain how that works to you. But I've got to run for this lunch," he said to The Huffington Post walking away quickly. "But I support his confirmation."

Back in November Toomey said he was pleased that Obama nominated Judge Restrepo.

“As both a federal magistrate and district judge, Judge Restrepo has served the people of Pennsylvania honorably and with distinction.  He also is dedicated to his community by giving his free time to the Make-a-Wish Foundation.  Sen. Bob Casey and I recommended Judge Restrepo to the White House for a seat on the federal district court, and I believe that he will also make a superb addition to the Third Circuit based in Philadelphia," Toomey said.

Fast forward six months on the issue.  "I will be submitting it (the blue slip) at the appropriate time," he said to The Huffington Post.
