Paul told Politico that he had concerns about Barr’s record on privacy, calling him a “chief advocate for warrantless surveillance of U.S. citizens.”
A spokesman for Paul didn’t immediately respond to a request for comment. The libertarian-leaning GOP senator had previously raised concerns about Barr, who also served as attorney general to President George H.W. Bush.
His opposition comes as the full Senate could take up Barr’s nomination as soon as this week following his approval by the Judiciary Committee last Thursday on a party-line vote.
