The right-leaning Judicial Crisis Network is starting a $140,000 ad campaign to help confirm Joan Larsen as President Trump's nominee for the 6th Circuit Court of Appeals.

The ad encourages Michigan's U.S. senators not to block the Michigan Supreme Court justice's confirmation to the federal appeals court.

"Justice Larsen — overwhelmingly re-elected, she applies the law, not a political agenda," a narrator says in the new 30-second ad set to run in Michigan. "Why aren't Sens. [Debbie] Stabenow and [Gary] Peters supporting her nomination to the U.S. Court of Appeals? Partisan politics. Tell Sens. Stabenow and Peters: End the political games. Support Joan Larsen."

Trump included Larsen on his shortlists for the Supreme Court vacancy created by the death of Justice Antonin Scalia. Larsen is a former Scalia law clerk and delivered a tribute to him at a memorial service featuring several of the high court justices last year.

"Justice Joan Larsen is one of the most impressive lawyers of her generation, yet Sens. Stabenow and Peters are holding up her nomination for petty political reasons," said Carrie Severino, Judicial Crisis Network chief counsel and policy director. "By obstructing this exceptionally qualified woman, Sens. Stabenow and Peters are proving yet again that they would rather carry water for Washington special interests than represent the people of their state."

The Judicial Crisis Network spearheaded a multimillion-dollar push to confirm Justice Neil Gorsuch to Scalia's vacant seat on the U.S. Supreme Court. Its new ad buy shows that it is beginning to take a larger role in the effort to confirm Trump's lower court nominees as well.
