Rudy Giuliani has pulled off a feat of endurance—he's managed to hang on as Donald Trump's personal lawyer for almost a year and a half without getting fired or resigning. But the strain may be taking a toll on him, especially now with the rising pressure from House Democrats announcing an impeachment inquiry.

The incident that finally got House Speaker Nancy Pelosi to pull the trigger and make an impeachment inquiry announcement was a reported whistleblower account of Trump pressuring Ukrainian president Volodymyr Zelensky to investigate the business dealings of Hunter Biden, former vice president Joe Biden's son—the whistleblower complaint still hasn't been released to Congress. In a new story in the Washington Post, Giuliani, in particular, is coming under scrutiny for reportedly pushing Trump to exploit relations with Ukraine for political gain. One anonymous U.S. official told the Post that: "Rudy—he did all of this. This shitshow that we’re in—it’s him injecting himself into the process."

On Tuesday night, Giuliani told Fox News host Laura Ingraham that he injected himself at the State Department's bidding. "You know who I did it at the request of? The State Department. I never talked to a Ukrainian official until the State Department called and asked me to do it. And then I reported every conversation back to them," he said. He then held up his cellphone as proof.

Giuliani made the same comments Monday when talking to Sean Hannity. The State Department has denied the claim, but Secretary of State Mike Pompeo dodged a question about it in an interview, a spokesperson for the department told The Hill, "Mr. Giuliani is a private citizen and acts in a personal capacity as a lawyer for President Trump. He does not speak on behalf of the U.S. Government."

Also on Ingraham's show, Giuliani lost his cool and started yelling at radio host Christopher Hahn: "Shut up, moron. Shut up. Shut up. You don’t know what you’re talking about. You don’t know what you’re talking about, idiot."

"I understand why Rudy is testy, given that the WaPo article shows very clearly that he is being positioned as the fall guy for this entire enterprise," tweeted MSNBC host Chris Hayes after the exchange. Later that night, Giuliani tweeted, "Democrat party is covering up a pattern of corruption involving high level members of the Obama cabinet. The multi-million and billion dollar pay-for-play is mind boggling. Biden Family sale of office to Ukraine was not the only one or the most egregious. Slimy Joe is not alone." The exact time stamp was 1:03 AM, and the fact that Giuliani was up that late might account for his bonkers appearance on Fox News Wednesday morning.
