Trump's ties to Communist baiting attorney Roy Cohn in the 1960's probably explains Trump's bombastic style. Cohn was a hard ass vicious, intimidating attorney who led the attempt by Senator McCarthy to try to get convictions for numerous Hollywood entertainers and film makers during the Communists 'scare" of the 1960's. Cohn was also Trump's hired gun in the numerous law suits that Trump filed against lenders, contractors, and tradesmen, when he failed to pay them for their work.
