A couple of weeks ago, Hillary Clinton claimed Democrat presidential candidate Tulsi Gabbard is secretly a Russian asset working to undermine the party’s 2020 primary.

Now, she’s making the case that Trump lawyer and former New York City mayor Rudy Giuliani is possessed by aliens.

“Rudy Giuliani was a key player in all of this and you know him well from your time as a New York senator,” The Late Late Show host James Corden told Clinton during an appearance on Tuesday.

“Tell me, from your opinion, does his current behavior surprise you at all?” he asked.

“Totally, totally,” Clinton said.

“Really?” Corden replied.

“Yes, I mean, look, he, um, was a tough guy. He was a mayor. He was mayor during 9/11, I was a senator, I worked with him, and I don’t know what happened,” Clinton said.

“It’s almost like aliens have seized his brain.”

Clinton contends Giuliani, who is at the center of the president’s interactions with Ukraine that’s become the basis for the House impeachment inquiry, has literally lost his marbles.

“For the longest time, he was things that were demonstrably untrue. For example, uh, he said Hillary Clinton was never at Ground Zero, never saw her,” Clinton continued. “Then of course the internet started putting up pictures of me standing next to him … and so I’m looking at that and I’m thinking, ‘truly, he’s been possessed.’”

“I don’t understand when it happened, but it’s a very clear case of a man who has gone over the edge, probably pushed,” she said.

Corden joked about inviting Giuliani onto the show to do an exorcism.

“Rudy, if you’re watching, it would be a great taped bit,” he said.

The mockery comes as Trump’s personal attorney faces increased scrutiny for his role in U.S.-Ukraine relations and alleged attempts to convince prosecutors in that country to investigate Burisma, a natural gas company that paid former vice president Joe Biden’s son at least $50,000 a month.

Biden bragged on video during a foreign policy summit last year about threatening to withhold $1 billion in U.S. aid to pressure Ukraine into firing a prosecutor who was investigating the company for corruption.

On July 25, Trump spoke by phone with Ukrainian President Volodymyr Zelensky and asked him to look into Biden’s claims, which sparked allegations the president threatened to withhold aid to Ukraine until Zelensky made it happen.

Zelensky publicly stated he was not pressured by the call, countering the claims of quid-pro-quo, but Democrats in the House launched an impeachment inquiry nonetheless, focusing largely on a whistleblower complaint about the call and Giuliani’s interactions with officials in the country and at the state department.

Clinton, meanwhile, continues to hint at the possibility of a rematch with Trump during nonstop media appearances to promote a new book about “gutsy women.”

A new poll conducted by Harvard-Harris in late October found Clinton would be in a dead heat with Biden, who is currently leading two dozen Democrats, if she decided to join the race, The American Mirror reports.
