Hunter Biden, son of Democratic presidential candidate Joe Biden, visited China six times as a U.S. Secret Service protectee, forcing taxpayers to subsidize his travel.

The findings come from an explosive new senate report highlighting Hunter’s various international corruption schemes, ranging from Russia to China to Ukraine.

Of particular interest are his deals with the Chinese Communist Party, such as “BHR Partners,” a joint venture between Rosemont Seneca Partners, an investment fund founded by Hunter Biden and Obama-era Secretary of State John Kerry’s stepson in 2009, and the state-owned Bank of China. The billion-dollar fund was notoriously birthed less than two weeks Hunter traveled to China alongside his father and then Vice President.

The new report, however, reveals Hunter visited China with taxpayer-subsidized travel more than once.

Between April 2010 and May 2014, he visited China at least six times with Secret Service protection. He visited Beijing, home to the Chinese Communist Party’s headquarters, five times and Shanghai once.

“According to U.S. Secret Service records, Hunter Biden enrolled as a protectee starting in January 2009, after his father was elected vice president. He remained a protectee for about 4.5 years, and records indicate an extensive amount of scheduled foreign travel as a protectee. Although the majority of his trips were domestic, the Committees identified nearly 70 trips that Hunter Biden scheduled to foreign countries while he was a protectee. Hunter Biden, here identified by the USSS using his full name, Robert H. Biden, scheduled foreign travel as a protectee to a wide array of foreign cities,” the report noted.

Prior reporting has estimated Hunter’s business trips have cost U.S. taxpayers nearly $200,000.
