One year into her tenure on the U.S. Court of Appeals for the D.C. Circuit, Judge Neomi Rao has found herself at the heart of crucial rulings on the U.S. House’s oversight powers—on the dissenting side.

Rao was the dissenting judge in the court’s October ruling that upheld the House Oversight and Reform Committee’s subpoena for President Donald Trump’s tax documents from Mazars. She was also one of three judges who would have granted an en banc rehearing of that case. Then on Tuesday, she again penned a dissent, this time in the House Judiciary Committee’s application to get grand jury materials redacted from special counsel Robert Mueller’s report.
