Mitt Romney says that if he worried about what reporters thought of him, he wouldn't get much sleep.
He says he's sleeping just fine.
He says the media tried a similar criticism of President George H.W. Bush. Romney says Bush "was a pretty great president" who was not a wimp.
A 1987 Newsweek profile featured a profile of then-Vice President Bush with the title — "Fighting the 'WimpFactor.'"
Asked whether he had ever been called a wimp, Romney says the Newsweek cover is a first.
Romney is in Israel on an international trip set to introduce him on the world stage.
