During Devon Archer's testimony Monday, the former business associate of Hunter Biden said the president's son and Burisma executives "called D.C." about Ukrainian prosecutor Viktor Shokin in 2015, who was ultimately fired. Although many Democrat lawmakers and pundits have defended President Biden, Rep. Pat Fallon, R-Texas, argued that Archer's claims were "absolutely a smoking gun" in the Biden family scandal on "The Faulkner Focus" Tuesday.

BIDEN KNEW EXACTLY WHO HIS SON WAS GETTING MILLIONS FROM: HOUSE OVERSIGHT CHAIRMAN JAMES COMER

PAT FALLON: It's absolutely absurd. Viktor Shokin was the prosecutor-general in Ukraine who Joe Biden got fired, withholding $1 billion dollars worth of aid. He [Shokin] was going after [Burisma owner Mykola] Zlochevsky, he had seized four of his homes, two plots of land and a Rolls-Royce. And a month later, he was fired and then that billion dollars was released. So, I think that is absolutely a smoking gun. And so many folks now can read the 1023, the FBI form where Zlochevsky told the confidential informant, who's very reliable, according the FBI, that he gave Hunter $5 million and Joe $5 million. He had phone calls directly with Joe Biden and it would be OK because he was going to get the prosecutor off their back. He did. … To this day, Burisma was never investigated again, so the Bidens delivered. … [Joe Biden] should have been nowhere near that. Instead, he was right in the thick of it.

5 KEY TAKEAWAYS FROM EXPLOSIVE WITNESS ACCOUNT OF HUNTER BIDEN'S FOREIGN BUSINESS DEALINGS, JOE'S ROLE

In a closed-door hearing Monday, Hunter Biden's former business associate, Devon Archer, spoke to House Oversight Committee members about the Biden family business dealings.

During the hearing, Archer testified that Hunter and top Burisma Holdings executives "called D.C." in 2015 to ask the Obama administration to help fire Ukrainian prosecutor Viktor Shokin.

Shokin was investigating Burisma for corruption.

At the time, though, then-Vice President Joe Biden was in charge of U.S.-Ukraine policy for the Obama administration.

A source said that Archer testified that just days later, on Dec. 9, 2015, Joe Biden traveled to Ukraine and made a speech. Biden, during the speech, said the government needed to fix the Ukrainian prosecutor's office.

The White House dismissed the "evidence-free" allegations in a statement to Fox News Digital.

"It appears that the House Republicans’ own much-hyped witness today testified that he never heard of President Biden discussing business with his son or his son’s associates, or doing anything wrong," White House spokesperson Ian Sams told Fox News Digital. "House Republicans keep promising bombshell evidence to support their ridiculous attacks against the President, but time after time, they keep failing to produce any."

"In fact, even their own witnesses appear to be debunking their allegations. Instead of continuing to waste time and resources on this evidence-free wild goose chase, House Republicans should drop these stunts and work with the President on the issues that actually impact Americans’ daily lives, like continuing to lower costs, create jobs, and strengthen health care," Sams said.
