President Donald Trump announced Judge Brett Kavanaugh as his nominee to the U.S. Supreme Court Monday, the president’s second nomination to the high court.

Kavanaugh currently serves as a judge on the U.S. Court of Appeals for the D.C. Circuit. He previously served as a counsel under Ken Starr during the investigation of President Bill Clinton and later worked in the administration of President George W. Bush. He began serving on the D.C. District Court in 2006.

Democrat Sherrod Brown issued a statement, saying “I have serious concerns about some of Judge Kavanaugh’s rulings against women’s rights and consumer rights…I plan to review his record thoroughly and ask him tough questions face-to-face before I make my decision.”

Republican Rob Portman said “Judge Kavanaugh has an impressive background. He his highly regarded as a fair-minded and independent judge and is clearly qualified to serve on the Supreme Court.”
