Republicans have long targeted the president’s son over his finances and other issues.
Republicans on the House Oversight Committee sent a formal request to Hunter Biden on Thursday for information and records related to his business dealings.
The panel is also seeking records from James Biden, the younger brother of President Joe Biden, and Hunter’s business partner, Eric Schwerin.
Republicans, including former President Donald Trump, have targeted Hunter Biden for years, but they have ramped up scrutiny after taking control of the House this year.
The committee gave the Bidens until Feb. 22 to respond before they decide whether to issue a subpoena.
The committee also held a hearing on Wednesday to investigate Twitter’s role in suppressing a story from the New York Post on Hunter Biden’s laptop. The committee’s chairman, Republican James Comer of Kentucky, accused the company of participating in a “coordinated campaign by social media companies, mainstream news, and the intelligence community to suppress and delegitimize the existence of Hunter Biden’s laptop.”
Yoel Roth, Twitter’s former head of trust and safety, said the company had concerns because the story “at first glance bore a lot of similarities to the 2016 Russian hack and leak operation targeting the DNC. We had to decide what to do. And in that moment, with limited information, we made a mistake.”
