The Donald's advice to Mitt Romney for Wednesday's debate against President Barack Obama: No more Mr. Nice Guy.
“I think the nice guy stuff is over,” Donald Trump told CNBC’s “Squawk Box” on Tuesday.
“I think it’s going to be a much different Mitt Romney,” the real estate magnate said.
“He’s going to be very strong and very smart, and he’s going to attack the president on what he can attack him on, which is the economy and jobs.”
Trump, who has been a vociferous critic of Obama, said he canceled a business trip to Europe in order to watch the debate. (Read More:Trump Now Taking Aim at Obama's Collegiate Background.)
