House Republicans do not have enough evidence yet to justify an impeachment of President Joe Biden, two legal scholars told a congressional panel Thursday as lawmakers sparred over the basis for the GOP-led impeachment investigation.

The first hearing on the high-profile probe quickly devolved into a partisan tit for tat at the House Oversight and Accountability Committee, as Republicans outlined the basis for their investigation while Democrats dismissed the inquiry as baseless.

House Republicans kicked off their first impeachment inquiry hearing Thursday laying out the allegations they will pursue against President Joe Biden, though their expert witnesses acknowledged Republicans don’t yet have the evidence to prove the accusation they’re leveling.

Thursday’s hearing in the House Oversight Committee didn’t include witnesses who could speak directly to Hunter Biden’s foreign business dealing at the center of the inquiry, but the hearing offered Republicans the chance to show some of the evidence they’ve uncovered to date.

George Washington University law professor Jonathan Turley, testifying during the first House impeachment inquiry hearing into President Joe Biden, said Thursday that while Washington, D.C., is “awash” with influence peddling, the “size and complexity” of the allegations against Biden and his family are unprecedented.

House leaders, he said, have a “duty” to determine if the president was involved in a pay-to-play scheme.
