Former New York Mayor Rudy Giuliani on Thursday spun a wild new conspiracy theory involving a bunch of Democrats and Ukraine and said they want to literally kill him over it.

Giuliani, the personal attorney to President Donald Trump , told Fox Business host Trish Regan he had smoking gun evidence of money laundering by Hunter Biden , son of Joe Biden , the former vice president now running for president.

Giuliani did not present such evidence, but read an email on his iPad that he said was between the governments of Latvia and Ukraine detailing a corruption affair involving the younger Biden.

He also said the plot runs even deeper.

Its not just Biden, he said. Bunch of Democrats. Thats why theyre so crazy on the subject of Ukraine, and why they want to literally kill me.

Trump was impeached for withholding U.S. aid to Ukraine to pressure the nation into digging up dirt on the Bidens.

He was acquitted by the GOP-led Senate.

Giuliani has claimed hes been doing his own investigation on Ukraine.

Sen. Lindsey Graham (R-S.C.), a prominent Trump defender, said Attorney General William Barr told him there would be an intake process for information from Giuliani on the presidents political opponents.

The House Judiciary Committee has complained that such a process is a significant departure from the departments traditional channels of investigation.
