(London Daily Mail) The chairman of the Republican National Committee has slammed Donald Trump for attacking Ted Cruz's wife Heidi on Twitter.
Reince Priebus told the Milwaukee-Wisconsin Journal Sentinel that discussing family members of political opponents should be off limits.
He called the attacks from the GOP front-runner 'not helpful' to the overall intent of the Republican party, but also dismissed its impact on the race as a media talking point.

'I believe that family members should be left out of the conversation.
'And I do think that overall some of these things are not helpful.
'But I also think that while we chat about how people should behave or not behave, I think most of it's just chatter,' Priebus told the Milwaukee-Wisconsin Journal Sentinel.
