Donald Trump admits he acted little childish
Donald Trump admitted Monday that his rhetoric on the campaign trail may not always sound entirely presidential.
"Probably is a little childish," Trump said in an interview with CNN's Erin Burnett at Trump Tower in New York. "But you know what? This is a campaign."
The billionaire businessman defended his style, saying the attacks he's unleashed on his rivals in the Republican presidential field have largely been reactive.
"I'm responding to them. I'm a counter-puncher," Trump said. "For instance, (Gov. Scott) Walker was very nice to me. All of a sudden, he hit me and I hit him back. All of these guys. (Sen. Marco) Rubio was very nice to me, couldn't have been nicer. All of a sudden a week ago he started hitting me."
Trump has taken shots at many of his competitors -- particularly going after former Florida Gov. Jeb Bush, Rubio and Kentucky Sen. Rand Paul in recent weeks.
He also frequently refers to Democratic front-runner Hillary Clinton as the "worst" secretary of state in the country's history -- a charge that he repeated on Monday.
"We look at the job that Hillary did as secretary of state -- she goes down as perhaps the worst secretary of state in history and when I run against her evenly in the polls, I'm doing very well against Hillary and beating her," Trump said.
