A Republican lawmaker turned heads on Monday with a stunning warning regarding a credible whistleblower who claims to have information about a bribery scheme involving President Joe Biden.

Florida GOP Rep. Anna Paulina Luna said the FBI is “afraid” that the source would be “killed if unmasked.”

“Just left meeting for House Oversight. The FBI is afraid their informant will be killed if unmasked, based on the info he has brought forward about the Biden family,” Luna wrote on Twitter.

She did not elaborate.

According to information previously obtained by Fox News Digital, the whistleblower who made the allegations regarding then-Vice President Biden’s alleged participation in a criminal bribery scheme with a foreign national has been identified as a “highly credible” FBI confidential source.

The individual has been actively involved in various investigative matters since the Obama administration, the report said.

The whistleblower claims that the FBI possesses a particular document known as an FD-1023 form, dated June 30, 2020, that allegedly contains explicit details provided by a confidential human source.

According to the information outlined in the document, it is alleged that during his tenure as vice president, Biden was involved in a criminal bribery scheme amounting to $5 million with a foreign national. The alleged purpose of this scheme was to exert influence over policy decisions.

Per Fox News:

A source familiar told Fox News Digital on Friday that the confidential human source who provided the Biden information to the FBI was a “pre-existing” FBI source who has been used in multiple investigative matters separate from the Biden information.

The source told Fox News Digital that the confidential human source was used by the FBI for “at least several years” before the generation of the June 2020 FD-1023 form detailing the Biden allegations.

The source also told Fox News Digital that the confidential human source has been “consistently reviewed by the FBI” and has been “found to be highly credible.”

The source said the individual participated in investigative matters during the Obama administration.
