Arizona Governor Jan Brewer and President Barack Obama gave one another a talking to when she met him on the tarmac outside of Phoenix on Wednesday.
The two leaders could be seen engaged in intense conversation at the base of Air Force One's steps.
Asked moments later what the conversation was about, Brewer, a Republican, said, "He was a little disturbed about my book."
Brewer recently published "Scorpions for Breakfast," which details her experiences growing u, and defends her signing of Arizona's controversial law cracking down on undocumented immigrants.
Obama has been openly critical of the law.
A White House official who spoke to Fox News on condition of anonymity said Obama objected to Brewer's description of a 2010 meeting they had on immigration at the White House.
"I felt a little bit like I was being lectured to, and I was a little kid in a classroom, if you will, and he was this wise professor and I was this little kid, and this little kid knows what the problem is and I felt minimized to say the least," Brewer wrote in her book.
She also described a terse meeting before Obama's commencement address at Arizona State University. "He did blow me off at ASU," she told reporters last November.
On the tarmac Wednesday, Brewer handed Obama an envelope with a handwritten invitation to return to Arizona to meet her for lunch and to join her for a visit to the border.
"I said to him, you know, I have always respected the office of the president and that the book is what the book is," Brewer told reporters Wednesday, confirming Obama complained that she described him as not treating her cordially.
"I said that I was sorry that he felt that way. Anyway, we're glad he's here, and we'll regroup," she added.
