Jeb Bush capped off a three-day swing through Iowa with a series of attacks on Donald Trump. The former Florida governor took to the radio and an appearance on cable television to slam Trump's candidacy.
Bush told WBZ radio that Trump's remarks on dealing with Russian President Vladimir Putin show why Trump should not hold the nation's highest office.
"The front-runner in your campaign, Donald Trump, says go ahead, let Russia bomb ISIS, but we have competing objectives there," said the Boston radio host.
"We do and that's why Donald Trump shouldn't be president of the United States. He has no clue what he's talking about," Bush said. "Putin is not interested in partnering with us to take out ISIS. He's there to prop up the brutal Assad regime."
