According to Fox News, a whistleblower recently told Republican members of Congress that the FBI has a document detailing criminal activity by President Joe Biden and members of his family.

Yet while the lawmakers say the evidence is enough to doom Biden, some critics wonder whether the Department of Justice is trying to bury it. 

House Oversight Committee subpoenas FBI document

The New York Post reported on Wednesday that the House Oversight Committee has issued a subpoena for an FD-1023 informant report that was "created or modified in June 2020.″

The Post quoted Oversight Committee Chairman James Comer as saying that the whistleblower's allegations raise "concerns that then-Vice President Biden allegedly engaged in a bribery scheme with a foreign national."

"The American people need to know if President Biden sold out the United States of America to make money for himself," he added.

What's more, Comer joined with Iowa Republican Sen. Chuck Grassley in co-writing a letter sent to Attorney General Merrick Garland and FBI Director Christopher Wray along with the subpoena.

"Unclear" if FBI investigated corruption allegations

"It has been alleged that the document includes a precise description of how the alleged criminal scheme was employed as well as its purpose," they wrote.

"Based on the alleged specificity within the document, it would appear that the DOJ and the FBI have enough information to determine the truth and accuracy of the information contained within it," Comer and Grassley stressed.

"However, it remains unclear what steps, if any, were taken to investigate the matter," the conservative lawmakers went on to point out.

Meanwhile, members of the Post's editorial board went further in a piece published on Thursday, suggesting that the DOJ could be protecting the president.

The editorial board wonders "how many whistleblowers may have been squelched"

"Maybe the FBI did act on the new whistleblower’s charges, but didn’t find enough evidence. Or maybe Justice prosecutors are hard at work putting together a case," they wrote.

"But the Biden’s Justice Department is hard to trust, politicized under Garland to target parents who speak up at school board meetings and even traditionalist Catholics," the editorial board continued.

"And, apparently, to ignore all the rich material suggesting Biden-family crime involving China, Ukraine, Russia, Romania and Mexico (for starters)," they continued.

"We have no idea how far Comer & Co. will get in ferreting out the truth from Justice on these or any other allegations," the editors acknowledged, adding, "But it sure makes you wonder how many whistleblowers may have been squelched already."
