The Republican National Committee whacked back at new Democratic National Committee chairman Tom Perez for saying that President Trump 'didn't win this election.'

The RNC sent out a statement Sunday morning labeling his comments 'unhinged.'

'Chairman Perez's comments are dangerous and undermine our democratic process,' said chairwoman Ronna Romney McDaniel. 'Perhaps Mr. Perez needs a lesson on how the Electoral College works but whether he likes it or not, Donald Trump is our president.'

'He should be ashamed of himself for insulting the millions of Americans who don't share his liberal vision for our country,' she continued. 'The Democrats are the minority party because of comments like those, and if he thinks this is the way back from the wilderness, he's sorely mistaken.'

'Mr. Perez should apologize and Democrats should denounce the rhetoric coming from this new leader of their Party,' McDaniel added.

On Friday night, Perez worked up a crowd in Newark, New Jersey, unleashing a tirade against the Republican Party.

The labor secretary under Obama shouted: 'Donald Trump, you don’t stand for our values. You didn’t win this election.'

His audience cheered as Perez told those at the rally hosted by the New Jersey Working Families Alliance that the GOP doesn't 'give a s**t about people.'

Perez encouraged Democrats to resist Trump and his policies and referred to the president's reign in the White House as being 'a bully in Washington'.

The politician was elected to the role in February and said to the Newark, New Jersey, crowd: 'Donald Trump, you don’t stand for our values. You didn’t win this election'

Perez also praised those who marched against the president and his administration on January 21, the day after the inauguration, The Daily Caller first reported.

He was elected in late February to replace interim chair Donna Brazile, who filled the position after former chair Rep. Debbie Wasserman Schultz stepped down just before the Democratic National Convention last summer.

The politician said in the speech: 'Donald Trump, that romance you have with Putin, it's not gonna do you any good, because we will resist.

'One week ago we did, and we did so successfully. Donald Trump wants his name around everything... but when it came to healthcare, he didn't want Trumpcare.

'So what do we call it? Trumpcare.... I'll tell you my idea.. you know what's my idea for a program? "I Don't Care," because they don't care about people.'

At the end of his impassioned tirade, Perez said he wanted to make the fiery remarks in New Jersey because he wanted to 'learn about bullies' to help stop the 'bully in Washington', reported Fox News Insider.

After he was chosen for the DNC role, Perez asked every member of staff to send in a resignation letter as he plans for a major overhaul of the party's organization, it was revealed on March 28.

It will give him the chance to completely remake the DNC's headquarters from scratch after it was damaged by hacks and accusations of favoritism during the disastrous 2016 election campaign.

Every employee has been asked to submit their resignation letter by April 15, multiple sources told NBC News.
