Trump officials considering Mar-a-Lago for the next meeting with China Xi: report MORE & # 39; s authorized attorney general, becoming the first Republican to come out as a "no" vote on William Barr.

Paul told Politico that he worried about Barr's record of privacy and called him a "senior lawyer for independent oversight of US citizens."

A Paul spokesman did not respond immediately to a request for comment. The libertarian-leaning GOP senator had previously expressed concern about Barr, who also served as Attorney General of President George H.W. Bush.

His opposition comes because the entire Senate could take up the appointment of Barr as soon as this week after his approval by the Judiciary Committee last Thursday on a party line vote.

Paul's "no" voice is not enough to make Barr disappear. Republicans have a 53-47 majority, which means that if the Democrats could unite their entire party, they would still have to turn four Republican senators to block the confirmation.

Sen Doug Jones (D-Ala.) Became the first Democrat who said last week that he would support Barr.

Jones & # 39; s and Paul's outflows mean that Democrats still have to reverse four Republicans to stop the nomination. Other potential swing votes, including Sen.
