House Oversight and Accountability Committee Chairman James Comer (R-Ky.) said “over 50 percent” of a new form regarding allegations about President Joe Biden’s family business dealings and potential bribes was redacted.

The FD-1023 form is a type of document used by the Federal Bureau of Investigation (FBI) recording allegations about potential criminal activity from the FBI’s confidential human sources.

Evidence unearthed through an earlier FD-1023 submitted by a trusted FBI informant alleges that the president accepted at least $5 million as a bribe from a foreign national. Still, more recent allegations put that figure to at least $10 million, partly through the use of shell companies.

Republicans are investigating the matter amid concerns that Biden may have used his influence while vice president to assist his family’s business dealings, primarily those of his son Hunter Biden.
