Former House Speaker Newt Gingrich expressed regret that Donald Trump hasn’t acted in a more presidential manner as the presumptive Republican nominee, arguing that a little more “discipline” and “self-restraint” would go a long way as he seeks the nation’s highest office.

Gingrich told Fox News Tuesday afternoon that he wishes Trump were “10 percent more presidential,” adding that he doubts that will happen. He also told host Neil Cavuto that while Trump claims that he could be more presidential but decides against it because he’d be boring, a bit of “boredom” could go a long way and could help him be more of a role model for America’s youth.
