Former Italian Prime Minister Matteo Renzi has threatened a lawsuit against ex-Trump campaign aide George Papadopoulos over Papadopoulos’ allegation that Renzi attempted to undermine Trump’s 2016 presidential campaign.

Papadopoulos told Italian publication La Verita that Renzi was ordered by former President Barack Obama to “strike a blow” against Trump in the 2016 presidential election.

Renzi responded by taking to Facebook to call the accusation “seriously damaging.” He followed that up with a warning: “see you in court.”

“I’m accused of participating in an international conspiracy warp by Obama vs Trump,” he wrote, before directly telling Papadopoulos that their feud will end in court.

Papadopoulos doesn’t seem to be worried. He shot back on Twitter with his own warning: “good luck.”

“My response to the failed former Italian Prime Minister who is threatening to sue me: good luck,” he tweeted, “and in the meantime, cooperate with the investigations into the direction you took Italy in 2016, which is now under investigation for attempting to interfere in the 2016 election.”

He also seems to have confidence that the entire controversy will end Renzi’s political career.

“We will face these insults and false allegations in an Italian court,” Renzi tweeted to Papadopoulos.

Papadopoulos again reiterated that he is not worried and he is looking forward to the “discovery phase” of the potential trial, which he believes will validate his claims against Renzi.

“The discovery phase of this lawsuit from the failed former Italian prime minister should be very interesting!” he tweeted.

“In the meantime, cooperate with the investigations into the direction you took Italy in 2016, which is now under investigation for attempting to interfere in the 2016 election … I believe your hands should be full with John Durham and AG Barr,” Papadopoulos also wrote, referencing the Connecticut U.S. attorney who has been tasked with digging into the origins of the Russian collusion investigation, which seems to be a top priority for Attorney General Barr.

Papadopoulos is familiar with the court system since he pleaded guilty to lying to the FBI in 2017 about contacts with people who claimed to be in connection with top Russian government officials. Considering the investigation debunked conspiracy theories that Trump worked with Russia to interfere in the election, Papadopoulos is no doubt excited over an investigation into the origins of the entire clown show, even if it means getting sued by Renzi.
