Louisiana Sen. John Kennedy pushed Democrats to explain how they have confidence that Hunter Biden wasn’t corrupt if he was not investigated.

Kennedy, 68, noted that House Speaker Nancy Pelosi and House Intelligence Committee Chairman Adam Schiff have declined to call Biden in for questioning. Biden, 49, was hired to be a highly compensated board member of Burisma Holdings, a natural gas company in Ukraine when his father Joe Biden was leading U.S. policy in the region while serving as vice president under President Obama. President Trump requested an investigation into the Bidens during his July 25 phone call with the president of Ukraine.
