Two top Republican Senators are expanding their probe into potential conflicts of interest “posed by the business activities of Hunter Biden” as the Senate investigative committees continue to probe former Vice President Joe Biden’s son’s business activities overseas during his father’s tenure in the Obama Administration.

Sen. Chuck Grassley, Chairman of the Finance Committee, and Sen. Ron Johnson, who already have an ongoing investigation into numerous White House meetings during the Obama Administration with senior Ukrainian officials, sent a letter Wednesday to Secret Service Director James M. Murray requesting information “about whether Hunter Biden used government-sponsored travel to help conduct private business, to include his work for Rosemont Seneca and related entities in China and Ukraine.”

Grassley and Johnson say they want the information no later than February 19, according to the letter sent to Murray.

“The Committee on Finance and Homeland Security and Governmental Affairs (“the committees”) are reviewing potential conflicts of interest posed by the business activities of Hunter Biden and his associates during the Obama administration, particularly with respect to his business activities in Ukraine and China,” the letter states.

The two powerful GOP chairmen want “Hunter Biden’s travel arrangements to conduct business related to his dealings in Ukraine and China, among other countries, while he received a protective detail.” pPlease describe the protective detail that Hunter Biden received while his father was Vice President.

Please provide a list of all dates and locations of travel, international and domestic, for Hunter Biden while he received a protective detail. Please provide a list o f all dates and locations o f travel, international and domestic, for Hunter Biden while he received a protective detail. In your response, please note whether his travel was on Air Force One or Two, or other government aircraft, as applicable and whether additional family members were present for each trip.

The Senators also stated in the letter that they have sent other letters to other government agencies questioning ‘potential conflicts of interest’ regarding the deal during the Obama Administration’s Committee on Foreign Investment in the United States (CFIUS) approval to sell off 20 percent of U.S. uranium from the Canadian company that had assets in the U.S. to to the Russian energy giant Rosatom. The transaction required the the approval of CFIUS, the multi-agency approval committee. At the time Hillary Clinton was head of the State Department, which was a voting member of the CFIUS board.

“In addition to several letters that the committees have sent to other agencies as part of that inquiry, the Committee on Finance also has written to the Department of Treasury regarding potential conflicts of interest in the Obama-era CFIUS- approved transaction which gave control of Henniges, an American maker of anti-vibration technologies with military applications, to a Chinese government-owned aviation company and China-based investment firm with established ties to the Chinese government. That transaction included Rosemont Seneca Partners, a company formed in 2009 by Hunter Biden, Christopher Heinz, and others.”

The letter goes on to state that “in December of 2013, one month after Rosemont Seneca’s joint venture with Bohai Capital to form BHR, Hunter Biden reportedly flew aboard Air Force Two with then-Vice President Biden to China. While in China, he helped arrange for Jonathan Li, CEO of Bohai Capital, to “shake hands” with Vice President Biden.

Afterward, Hunter Biden, met with Li for reportedly a “social meeting.” After the China trip, BHR’s business license was approved.6 Then, in 2015, BHR joined with Aviation Industry Corporation of China (AVIC) to acquire Henniges, which was the “biggest Chinese investment into US automotive manufacturing assets to date,” Johnson and Grassley’s letter revealed.
