WASHINGTON — White House national security adviser Jake Sullivan refused to comment Friday about whether the Biden family’s business ventures in China posed a “national security issue,” as Republicans allege.

“Republicans on the House Oversight Committee are currently investigating the Biden family’s ties to foreign entities. They have specifically pointed to Hunter Biden’s financial ties to China,” began Daily Caller reporter Diana Glebova ahead of a Camp David summit with President Biden and the leaders of Japan and South Korea.

“Does the administration view this investigation as legitimate? And is the administration concerned that Hunter Biden’s ties to China pose a national security issue?”

“I don’t have any comment on that,” Sullivan replied.

President Biden, South Korean President Yoon Suk Yeol and Japanese Prime Minister Fumio Kishida were expected to focus largely on China during their Friday trilateral at the forested presidential retreat in western Maryland.

House Republicans accuse the president of abusing his prior position as vice president to advance his family’s business interests in countries where he led the Obama administration’s foreign policy, such as China, Russia and Ukraine.

The first family has had at least two major business relationships in China and Joe Biden allegedly was involved in both of them.

“We’re concerned that the president is compromised because of the millions of dollars that his family has received,” House Oversight Committee Chairman James Comer (R-Ky.) told CNN last week.

Former President Donald Trump, who is seeking a rematch against Biden in next year’s election despite facing four criminal trials, claimed in a video published Tuesday that Biden “was bribed and now he’s being blackmailed.”

“He’s petrified of China because they know exactly how much money has been given to him and they know exactly where it is. China has paid him a fortune,” claimed the 77-year-old, blasting Biden for failing to do more to investigate the origins of COVID-19, which killed more than 1 million Americans after possibly leaking from a Chinese lab — a theory backed by the FBI and Energy Department.

“Just think of what China has gotten for all that money. Biden shut down my administration’s initiative targeting Chinese spies in the United States,” Trump said. “He let China off the hook for COVID. He shut down the investigation into the origins of the China virus.”

Trump added, “He did nothing as China began setting up bases in Cuba, taking over South America and threatening Taiwan. They even took over the Panama Canal,” he added, referring to a series of Chinese investments in the formerly US-controlled canal zone.

The Chinese spy base in Cuba was set up in 2019 during Trump’s presidency, the Biden administration said.

Trump added, “He did nothing as China began setting up bases in Cuba, taking over South America and threatening Taiwan. They even took over the Panama Canal,” he added, referring to a series of Chinese investments in the formerly US-controlled canal zone.

“Russia and China are even doing military exercises near the Aleutian Islands right off the coast of Alaska and Biden sits back and his hands and does nothing,” Trump added.

Other Republicans have faulted Biden’s response to largely China-sourced fentanyl, which has caused a surge in US overdose deaths as the highly potent compound is increasingly mixed into non-opioid drugs and counterfeit prescriptions, killing unwitting users.

“Over the past few months, [Biden] sent three members of his administration to make nice with China and got nothing done on fentanyl.” Republican presidential candidate and former South Carolina Gov. Nikki Haley said earlier this month, referring to recent visits by Secretary of State Antony Blinken, Treasury Secretary Janet Yellen and climate envoy John Kerry.

Fentanyl killed an estimated nearly 76,000 Americans in 2022 — an all-time record — after killing about 72,000 in 2021.

The death toll from fentanyl under Biden is up dramatically.

During 2020, Trump’s final full year in office, roughly 58,000 Americans died from fentanyl, though that figure was up significantly from more than 37,000 in 2019 and about 32,000 in 2018.

Republicans also faulted Biden’s handling of a Chinese spy balloon that Biden ordered shot down in February off South Carolina’s coast after it traversed the continental US.
