Former GOP congressman and Jan. 6 select committee adviser Denver Riggleman now working with Hunter Biden

Former Republican Rep. Denver Riggleman of Virginia — who served as a senior technical adviser to the House select committee probing the Jan. 6, 2021, assault on the Capitol — is working with the legal team advising President Biden's son, Hunter Biden, who is facing increasing scrutiny from House Republicans over his business dealings. 

Riggleman's work with Hunter Biden is focused on assessing data issues, and he has assisted Biden's lawyers as they contend with congressional inquiries and evaluate GOP claims made about his conduct, according to three people with knowledge of the Biden legal team. 

Riggleman's work with Hunter Biden was confirmed on Tuesday by Kevin Morris, a lawyer and confidant of the president's son.
