"I am, and have been, the decision-maker on this case," Weiss said. "At no time was I blocked, or otherwise prevented from pursuing charges or taking the steps necessary in the investigation by other United States Attorneys, the Tax Division or anyone else at the Department of Justice."

Rep. Jerrold Nadler (D-NY), the ranking member on the committee, called Weiss' testimony a "waste of time."

"[Weiss] was very clear that no one told him what to prosecute and what not to prosecute. He made all those decisions himself, and he said that before," Nadler said. "And I mean, [Republicans] tried to get him to say anything, but they just go over and over and over again the same thing."

House Republicans disagreed with that sentiment, insisting that Weiss' testimony wasn't credible and that questions still lingered about political pressure from the White House on the DOJ's investigation into the president's son.

"The important thing is that he has no answers for why he would offer a misdemeanor plea bargain with no jail time to someone who committed felonies and exclude all unknown or yet-to-be-investigated crimes," Rep. Darrell Issa (R-CA) said. "It’s that lack of explanation that leads us to all the other questions of whether he was influenced by others or in consultation with others."

Hunter Biden is set to go to trial in 2024 on charges relating to gun possession and filing false statements after a plea agreement fell apart earlier this year. Weiss was appointed by former President Donald Trump in 2018 to be US Attorney for the US District Court in the District of Delaware. President Biden has kept him in that position.
