James Biden, the brother of President Joe Biden, abruptly changed course on claims he wasn’t involved in a business deal between Hunter Biden and a Chinese corporation after U.S. House investigators presented documents containing his signature, according to insiders familiar with his testimony.

The business deal, which took place in 2017, proposed a joint venture agreement between Biden associates and CEFC, a Chinese company linked to the country’s communist government. Documents from that time obtained by investigators revealed James Biden signed an agreement memorandum alongside Hunter and another associate, a discovery directly at odds with James Biden’s previous testimony that he had no knowledge of the deal.

House Oversight Chair James Comer (R-KY) has publicly detailed a network of shell companies that accepted profits from deals like the one with CEFC, doling out proceeds between other shells and ultimately family members including James and his wife Sarah. From there, bank records show, the couple forwarded $40,000 to President Biden’s personal bank account, labeling the transaction a loan repaymen
