"He gave me his number at the White House and told me to call him if I needed anything, and he absolutely means it. It's been very good working with the President and his administration." The remarks also prompted speculation that the straight-talking 50-year-old was keeping one eye on his own chances of running for the presidency in 2016 if Mr Romney should lose Tuesday's election.
