President Barack Obama's nominee was approved by the committee in a voice vote. The process now heads to the full Senate, where Sen. Lindsey Graham, R-S.C., and Sen. John McCain, R-Ariz., say they intend to hold up the nomination, the Washington news organization Politico reported.
Graham has vowed to block all presidential nominees in the Senate until the White House agrees to allow survivors of the 2012 attack on a U.S. diplomatic facility in Benghazi, Libya, appear before Congress, though Graham admitted, "Jeh, I think, is a good guy. It's nothing about him. I would support him."
McCain said he would hold up Johnson's nomination until he obtains more information on border security. In a letter to Johnson last week, McCain claimed to be frustrated by outgoing Homeland Security Secretary Janet Napolitano's "obdurate refusal to provide important, relevant information."
