Arizona Gov. Jan Brewer points at President Barack Obama after he arrived at Phoenix-Mesa Gateway Airport, Wednesday, Jan. 25, 2012, in Mesa, Ariz. Brewer greeted Obama and what she got was a book critique. Of her book. The two leaders engaged in an intense conversation at the base of Air Force One’s steps. Both could be seen smiling, but speaking at the same time. Asked moments later what the conversation was about, Brewer, a Republican, said: "He was a little disturbed about my book." Brewer recently published a book, "Scorpions for Breakfast," something of a memoir that describes her years growing up and defends her signing of Arizona’s controversial law cracking down on illegal immigrants, which Obama opposes. Brewer also handed Obama an envelope with a handwritten invitation for Obama to return to Arizona to meet her for lunch and to join her for a visit to the border. (AP Photo/Haraz N. Ghanbari)
