Republican Congressman Reid Ribble says he won't support presidential candidate Donald Trump, even if he's the party's nominee.
While some high-profile Republicans fear attacking Trump will alienate his supporters, the 8th District congressman is much more candid.
Ribble says Trump behaves like a "sixth-grader and appeals to "the worst parts of who we are as people."
In an interview with the Milwaukee Journal Sentinel Thursday, Ribble says he's appalled by Trump's inclination "to be as inflammatory as possible."
Trump's call for a ban on Muslims entering the U.S. has drawn criticism from inside the Republican Party.
But, many in the GOP are reluctant to take Trump on personally, saying they'll support the winner of the Republican nomination, whoever that turns out to be.
