Republican presidential candidate Donald Trump's new convention manager blasted rival Ted Cruz's campaign for using "gestapo tactics" to pick up delegates.
Paul Manafort appeared on NBC's "Meet the Press" on April 10 to talk about the billionaire's campaign, and accused Cruz of using "Gestapo tactics."
"He's threatening," Manafort said, CNN reported. "You go to these county conventions, and you see the tactics, Gestapo tactics, the scorched-earth tactics."
Trump himself blasted Cruz for picking up more delegates than him, criticizing the primary election system on Twitter.
"I win a state in votes and then get non-representative delegates because they are offered all sorts of goodies by Cruz campaign. Bad system!" he tweeted.
The Cruz campaign later responded to Trump's complaints.
"More sour grapes from Trump who continues to lash out in tantrums every time he loses. We are winning because we've put in the hard work to build a superior organization," Cruz spokeswoman Catherine Frazier said.
"We have earned our success by working hard to build a superior organization and are working within the process and rules that have been established -- which has led now to four consecutive wins, 12 wins total."
Following a Cruz victory in Colorado on April 9 -- in which the senator captured all 34 delegates from a series of congressional district meetings -- Trump again slammed Cruz and criticized the election system for being unfair.
"The people of Colorado had their vote taken away from them by the phony politicians. Biggest story in politics. This will not be allowed!" Trump tweeted, according to The Denver Post. That tweet was preceded by another, which questioned the relevancy of the voting process in the primaries.
"How is it possible that the people of the great State of Colorado never got to vote in the Republican Primary? Great anger -- totally unfair!" Trump tweeted.
In his "Meet the Press" interview, Manafort also downplayed reports of a power struggle within the Trump campaign -- which began when Trump expanded Manafort's role in the campaign and instructed him to report directly to him and not to his embattled campaign manager Cory Lewandowski.
"A lot of what's being talked about is much ado about nothing. Yes, there's a transition, it's a natural transition. Trump was doing very well on a model that made sense, but now, as the campaign has gotten to the end stages, a more traditional campaign has to take place," Manafort said.
