M. Obama: I keep my opinions to myself

First lady Michelle Obama says she's done "pretty well" at keeping her political opinions to herself -- but not always easily.

"I have learned from my husband, watching him, that it does require a great deal of patience to really feel the full impact of the work that you do on the ground," Mrs. Obama told ABC's Barbara Walters in a recent interview, notes Politico. "It doesn't happen right away."

President Obama said during the joint interview that his wife "has a bigger difficulty biting her tongue."

"I think I've done pretty well at that," the first lady replied.

"Not bad," the president said.

Later in the interview, Mrs. Obama confessed: "I have opinions."

Added the president: "She's got a few views."
