Even Rick Perry changes his mind.
At his confirmation hearing as President-elect Donald Trump's pick for Secretary of Energy, the former Texas governor said he no longer wants to do away with the department he once said should be eliminated.
Or, at least, that was something he tried to say.
In 2011, during one of his presidential campaign debates, Perry could only remember the names of two of the three agencies he wanted get rid of. The third agency is the very one he was chosen by Trump to head.
