WASHINGTON - Sen. Tom Coburn said today that he would likely oppose the nomination of Eric Holder to be attorney general. Coburn, R-Muskogee, sits on the Judiciary Committee, which is scheduled to vote on Holder's nomination next week. Coburn said Holder doesn't believe the Second Amendment guarantees an individual right to bear arms. And he said Holder, during questioning last week, had declined to say whether he would defend state right-to-carry laws. Coburn said he was also bothered by Holder's defense of former President Bill Clinton's clemency order for members of a Puerto Rican group that carried out murders and other crimes. Republicans have delayed a vote on Holder's nomination, but Coburn predicted that he would ultimately be confirmed by the full Senate. Meanwhile, Coburn said he is now the top Republican on the powerful Investigations subcommittee, which has jurisdiction to probe government mismanagement and fraud.
