Trump Rips Republican Party Over Delegate 'Shenanigans' (VIDEO)

Republican front-runner Donald Trump took a new round of shots at the GOP's nominating process Sunday, while his newly-hired convention manager Paul Manafort accused Trump's rival Ted Cruz of using "gestapo tactics" to earn delegate support at nominating conventions across the country.

Speaking to thousands packed in a frigid airport hangar in western New York, Trump argued anew that the person who wins the most votes in the primary process should automatically be the GOP nominee.

"What they're trying to do is subvert the movement with crooked shenanigans," Trump said. The real estate mogul compared himself to Democratic candidate Bernie Sanders, who is well behind Hillary Clinton in that party's delegate race despite a string of state wins.
