What happened to a circle is round, it has no end, that’s how long we’ll be friends? It turns out that circle ends after a dozen years together in the U.S. Senate. John McCain said on Fox News Sunday that he is “leaning” toward voting against his former colleague and fellow Republican Chuck Hagel for Defense secretary. McCain said that Hagel was “wrong” to vote against the Iraq War surge in 2007, and Hagel knows he is wrong but refused to admit it in his confirmation hearing last week. McCain and Hagel were once friends in the Senate, and are both Vietnam War veterans. Hagel’s aides, though, insisted on Friday that he will not withdraw his name for the position.
