House Oversight Committee Chairman James Comer voiced his astonishment Monday night at charges filed by federal prosecutors against Hunter Biden informant Gal Luft.

Luft, who alleged there was evidence linking the first son to questionable business endeavors in China, faces eight counts — including acting as an unregistered foreign agent of Beijing — in an indictment unsealed Monday in the Southern District of New York.

“It’s just amazing the Department of Justice moves so quickly against some people,” Comer (R-Ky.) told Fox News host Laura Ingraham, later adding: “The timing is always coincidental, according to the Democrats at the Department of Justice.”

Luft claims that he gave investigators information on the Biden family’s activities in China in March 2019 and was concerned about the future first family potentially being compromised.

“He was getting paid, like the Bidens, from CEFC,” Comer said of Luft, referencing the Chinese energy giant that did business with both Hunter Biden and first brother James Biden.

“Anyone who says we shouldn’t take Gal Luft’s allegations seriously discounts the fact that the Bidens wanted to share office space with CEFC, even going so far as to say that Hunter wanted to make an extra set of keys for both Joe Biden, Jill Biden, and the president’s brother Jim Biden,” the lawmaker went on.

Comer stressed that he wanted to hear more about Luft’s accusations and review FBI notes in the case.

Luft, a dual citizen of Israel and the US, also stands accused of seeking to skirt sanctions on Iranian oil and orchestrate Chinese arms sales to multiple countries without the proper permits. He was arrested in Cyprus this past February and jumped bail while awaiting extradition. His current whereabouts are unknown.

Both Comer and House Judiciary Committee Chairman Jim Jordan (R-Ohio) also ripped into an old colleague who is now working with Hunter Biden’s legal team.

Former Rep. Denver Riggleman (R-Va.), who previously served as an adviser to the House select committee investigating the Capitol riot, openly questioned the authenticity of the first son’s laptop and shrugged off whistleblowers in the case as “credulous idiots,” “liars” or “grifters” in an interview with CNN Sunday.

“He should be ashamed for trying to discredit whistleblowers. We want whistleblowers to come forward,” Comer said. “These whistleblowers are credible. They’ve never had a blemish on their records. Everything they testify under oath … we’ve been able to back up with bank records in our investigation.”

Jordan pointed to the track record of IRS supervisory agent Gary Shapley, one of two whistleblowers who testified before Congress about alleged political interference in the federal inquiry into Hunter Biden.

“Gary Shapley, 14-year veteran, handled the biggest tax fraud cases — international tax fraud cases — he sure seems credible to me,” Jordan said.

The Ohio congressman also emphasized that CBS News did a forensic analysis of the laptop’s hard drive and was able to confirm its authenticity.

“If it’s not Hunter Biden’s laptop, why doesn’t he say so? I mean, that’d be the first thing I would do. I say, ‘That’s not my laptop,'” Jordan said. “Because it is his laptop and anyone with common sense and any bit of reason and logic can see that.”

Riggleman also told CNN’s Jim Acosta on Sunday that the first son’s team has evidence of “specific instances of fabrication or manipulation of the data,” though it was not immediately clear to what he was referring.

Shortly after The Post broke the news about the laptop in October 2020, social media companies such as Twitter throttled the bombshell story, while 51 former intelligence officials signed on to a letter claiming it possessed “all the classic earmarks of a Russian information operation.”

In the time since, numerous media outlets, including the New York Times, the Washington Post, Fox News and the Washington Examiner, have corroborated the laptop’s content.

Riggleman also accused the GOP of making sweeping claims based on shaky information.

“A lot of the other so-called whistleblowers, only if you want to define them as that — it seems like they’re always wrong. Either, you know, witnesses turn up missing or dead or somehow the data just disappears into the twilight,” he said in the interview.

This appears to be a reference to Comer admitting publicly back in May that his committee “can’t track down” an informant who alleged corruption by the Biden family.

Earlier this year, Comer pursued access to an official form detailing allegations of a Biden family bribery scheme from a confidential source, known as an “FD-1023.” 

Congressional Republicans who gained access to the file alleged that it detailed two $5 million transactions — one to Joe Biden and the other to Hunter Biden — from the owner of Ukrainian natural gas company Burisma Holdings.

“Riggleman is what CNN and other liberal media outlets love. He’s a disgruntled Republican that they can get on their TV show to trash other Republicans,” Comer said.

Riggleman revealed that he was working with Hunter Biden’s legal team last week, after court documents showed that the first son had reached a plea agreement with federal prosecutors.

As part of the agreement, the younger Biden will plead guilty to misdemeanor counts of willful failure to pay his federal income taxes in 2017 and 2018, according to court documents. 

He will also enter a pretrial diversion agreement for a felony charge over his possession of a firearm while addicted to illicit drugs.

Hunter Biden is due to appear in Wilmington, Del., federal court July 26.

Riggleman did not immediately respond to a request for comment.
