"I want to make sure we send a very clear signal," he said. "This was an assault on our democracy and we have to protect that."

"I'm punching back not only for my colleagues, I'm punching back for democracy," he continued.

Perez's comments come after the DNC announced last week it was suing Russia, the Trump campaign and WikiLeaks over alleged election meddling by Russia, saying the three actors worked to help President Trump Donald John TrumpOmar fires back at Trump over rally remarks: 'This is my country' Pelosi: Trump hurrying to fill SCOTUS seat so he can repeal ObamaCare Trump mocks Biden appearance, mask use ahead of first debate MORE win the 2016 election.

The complaint was filed in a federal district court in Manhattan.

The lawsuit identifies as defendants various Trump campaign aides who met with Russian nationals during the campaign, including former Trump campaign chairman Paul Manafort and Trump campaign adviser Richard Gates, both of whom have since been charged in special counsel Robert Mueller’s investigation into Russian meddling.

Gates is cooperating with the special counsel while Manafort is battling the charges against him in court.

Trump pushed back against the lawsuit in a tweet on Friday.

"Just heard the Campaign was sued by the Obstructionist Democrats. This can be good news in that we will now counter for the DNC Server that they refused to give to the FBI, the [former DNC chairwoman] Debbie Wasserman Schultz Deborah (Debbie) Wasserman SchultzFlorida Democrat introduces bill to recognize Puerto Rico statehood referendum Five things to watch at the Democratic National Convention Michelle Obama wishes Barack a happy birthday: 'My favorite guy' MORE Servers and Documents held by the Pakistani mystery man and Clinton Emails," he tweeted.

Perez told ABC News's George Stephanopoulos on Sunday that he was not worried by Trump's tweet.

"You know the beauty of the civil justice system, which is why I believe in it, George, is it's not trial by tweet.

"What Donald Trump said was very similar to what the Nixon administration said in 1972 when the DNC served them with a lawsuit then," he added. "So, they're in good company with the Nixon administration."
