Republicans on the House Intelligence Committee have criticized Democrats for not investigating the Bidens and their connection to Ukraine. Hunter Biden served on the board of Burisma, a Kyiv-based natural gas holding company, while his father was vice president.

In 2016, Joe Biden pushed for the dismissal of Prosecutor General Viktor Shokin as prosecutor, citing concerns he was ignoring corruption in his own office, and threatened to withhold aid to Ukraine if the Shokin was not fired.
 
There is no evidence that Joe Biden was acting in the interest of his son, and he has consistently denied allegations that he was motivated by family considerations.

Trump, meanwhile, has pointed to debunked allegations that Ukraine interfered with the 2016 elections.

On Thursday, Trump's former National Security Council adviser on Russia, Fiona Hill, chastised Republicans for promoting the conspiracy theory.

"Please [do] not promote politically driven falsehoods that so clearly advance Russian interests," Hill said during her testimony. "The fictions are harmful even if they are deployed for purely domestic political purposes."
