Former Florida Gov. Jeb Bush on Thursday explained why he was seen standing on his tiptoes for a group photo at the second GOP debate the previous night.

"Were you looking for someone or were you looking to be a little taller than the guy to your right?" Fox News host Bill Hemmer asked Bush on "America's Newsroom."

"I was looking over the press to see where my wife was sitting because she's the love of my life and I just need to have eye contact with her before we started," Bush explained.

"You've been married 42 years — that's the kind of thing you do," Bush said smiling, about his wife Columba Bush, who was in the audience at the Ronald Reagan Presidential Library.

At 6 feet 3 inches, Bush, already the tallest of the top 11 candidates on stage for Wednesday's prime-time debate, was seen standing on his toes for the group photo.

The former governor was flanked by Donald Trump, a chief rival and the current front-runner, who reportedly stands at 6 feet 2 inches, and Wisconsin Gov. Scott Walker, who is slightly shorter.

At the far end of the group photo stood two candidates from the undercard debate, former New York Gov. George Pataki and former Sen. Rick Santorum (R-Pa.), who stand at 6 feet 5 and 6 feet 4, respectively.
