CHARLOTTE, N.C. (AP) — Michelle Obama's brother says the first lady was reluctant to enter politics, but she is thriving as 'mom-in-chief.'

Craig Robinson tells NBC's "Today" his sister wanted a normal childhood for her daughters with the values of education and hard work she grew up with.

Robinson says there was a question about whether it was possible in the White House.

But he says that once she realized it was, she became more confident and began to thrive in the role of 'mom-in-chief.'
