Late Wednesday afternoon, Senate Finance Committee Chairman, Chuck Grassley, and Senate Homeland Security and Governmental Affairs Committee Chairman, Ron Johnson, released a letter penned to the U.S. Secret Service seeking Hunter Biden’s travel records while under their protection. This, they say is part of an ongoing investigation into potential conflicts of interest by Hunter Biden to boost business ventures in the Ukraine and China. They are specifically seeking details of the protection during the time period his father, Joe Biden, was Vice President and whether or not government-sponsored travel was used to conduct private business. Records show that Hunter Biden routinely flew on Air Force Two with his father to China, which resulted in favorable business dealings for the younger Biden. The two chairs had previously requested meeting records from the State Department, National Archives and Blue Star Strategies, which is a lobbying organization employed by Burisma Holdings, a Ukrainian energy company that employed Hunter Biden on its board at the same time Joe Biden oversaw the Obama Administration’s Ukraine policy. At that time, Burisma was under investigation for corruption. Grassley says he had previously raised concerns about the Obama administration’s approval of the sale of a U.S. company to the Chinese government and an investment firm formed, in part, by Hunter Biden.
