Mitt Romney links Donald Trump to 'trickle-down racism'

Mitt Romney, the former Republican presidential candidate, has condemned Donald Trump for setting a dangerous example for Americans by promoting "trickle-down racism".
Speaking in Utah at his annual business and politics summit on Saturday, Romney said the Republican Party must look beyond this presidential election to find its future.
Still, Romney insisted he understood those that have decided to back the presumptive Republican nominee, and said that he wouldn't be spending the next six months trying to convince anyone not to vote for Trump.
