GOP Senators Seek Hunter Biden's Travel Records for Probe

Sen. Chuck Grassley, R-Iowa, and Sen. Ron Johnson, R-Wis., said they have asked the U.S. Secret Service to provide Hunter Biden's official travel records for their investigation into "potential conflicts of interest."

Grassley, chairman of the Finance Committee, and Johnson, chairman of the Homeland Security Committee, wrote in a statement they are seeking details on Hunter Biden's travel dates and locations when he had Secret Services protection because his father Joe Biden was vice president.

Hunter Biden served on the board of Burisma Holdings, a Ukrainian energy company that had been embroiled in controversy, while his father oversaw U.S. policy on Ukraine.

Republicans argued during Trump's impeachment trial, if Democrats were allowed to call witnesses, the GOP should be able to call Joe and Hunter Biden. Democrats said the Bidens had no knowledge about whether Trump improperly pressured Ukraine to investigate the Bidens after Joe Biden began running for president.
