Ex-Trump Homeland Security adviser rips Giuliani, calls claim Ukraine hacked DNC a 'conspiracy theory'

A former Homeland Security adviser in the Trump administration said Sunday that the unsubstantiated claim that Ukraine was responsible for the hack of the Democratic National Committee (DNC) in 2016 is a "conspiracy theory" with "no validity."

Tom Bossert, who served in the administration between 2017 and 2018, made the comments on ABC's "This Week" while condemning Trump's personal attorney Rudy GiulianiRudy GiulianiCourt sets Smartmatic dismissal date on Giuliani, Bartiromo, others Ukraine sanctions two businessmen tied to Giuliani Mo Brooks accuses Swalwell attorney who served papers on his wife of trespassing MORE for "repeating the debunked theory" related to Ukraine and the DNC server to the president. 

The comments from Bossert came in light of revelations that Trump addressed the hack of the DNC during a July 25 phone call with Ukrainian President Volodymyr Zelensky. 

"It’s not only a conspiracy theory. It is completely debunked," Bossert said, adding that he communicated this to Trump during his time working in the administration. 

"At this point, I am deeply frustrated with what [Giuliani] and the legal team are doing and repeating that debunked theory to the president," Bossert added. "It sticks in his mind when he hears it over and over again, and for clarity let me just repeat that it has no validity.


"The United States government reached its conclusion on attributing to Russia the DNC hack in 2016 before it even communicated it to the FBI, long before the FBI ever knocked on the door at the DNC," Bossert said.

Giuliani pushed back just moments later while appearing on ABC, saying that Bossert "doesn't know what he's talking about."

Trump is facing mounting scrutiny over revelations that he sought to enlist Ukraine's help investigating Democratic presidential candidate Joe BidenJoe Biden 64 percent of Iowans say 'time for someone else' to hold Grassley's Senate seat: poll Philadelphia shooting leaves 2 dead, injures toddler Ron Johnson booed at Juneteenth celebration in Wisconsin MORE and Biden's son. A whistleblower complaint released last week accuses Trump of repeatedly pressuring the leader of Ukraine to open an investigation into the Bidens over unsubstantiated allegations of corruption.

It also shows that Trump called on Zelensky to look into matters related to CrowdStrike, a U.S.-based internet security company that initially examined the breach of the DNC's servers in 2016, after the Ukrainian leader asked about buying U.S. anti-tank missiles. CrowdStrike determined in 2016 that Russian agents broke into the DNC's network and stole emails that were later released by WikiLeaks. 

The request was an apparent reference to a conspiracy theory that casts doubt on the assessment that Russians were responsible for hacking the DNC.

Trump has responded by repeatedly railing against Democrats and the media. 

He has also questioned the loyalty of the whistleblower, saying last week at a private event that the whistleblower and the White House officials who gave the figure information were "almost" spies, according to a recording obtained by the Los Angeles Times.
