House Speaker Kevin McCarthy threatened an impeachment investigation if the Department of Justice used David Weiss' special counsel status to obstruct an investigation by the House Oversight Committee.

Attorney General Merrick Garland appointed Weiss as special counsel to investigate allegations against Hunter Biden on Friday, as The Daily Caller reported.

Biden pleaded not guilty to all charges on July 26, after United States District Judge Maryellen Noreika rejected the initial plea agreement and a more limited revision.

“The only reason you know of all this information is because we took the majority and we’re holding the administration accountable,” McCarthy told Fox Business host Larry Kudlow. “It is appalling of what we have learned.

"It is different than what President Biden had told us. He told us he had never talked to his son about any business dealings, that he has never been involved in his family’s business, that they never received any money from China.

"We now learn while he was vice president the family created 20 shell companies, they did receive more than a million dollars from China and he did call in to the business meetings and he did go to dinners.

"These dinners were very profitable. They got a new Porsche, they got $3.5 million, but the really most compelling thing here is there is somebody lying.”

The House Oversight Committee disclosed bank records on August 9 indicating that Hunter Biden received millions of dollars from Russian oligarch Yelena Baturina, who was married to deceased Moscow mayor Yuri Luzhkov until his 2019 death.

"The House Oversight Committee identified payments to the Biden family totaling approximately $20 million.

“We wanted to have a special prosecutor back in February but we were told by Garland that there was no need for one,” McCarthy said.

“David Weiss told us he could do it if he wanted, but what he told us privately with the IRS agents and what he told publicly along with the attorney general Garland, somebody is lying in this process and the only thing I realize here is the only stories that have not changed are the whistleblowers from the IRS. Their story has held up time and again.”

During a House Oversight Committee hearing on July 19, Internal Revenue Service whistleblowers Gary Shapley and Joseph Zeigler testified about interference with the investigation into President Biden.

“If the Biden Administration continues to fight to withhold information that could really clear all this up, did they take bribes, did they deal in the business, if they hold that up, we would have to move into the impeachment inquiry, which you know, Larry gives us apex of power to Congress and subpoena power and others to get us the documents we need, the bank statements, the credit card statements and others,” McCarthy said.

“Show us where the money went. Show us where you’re taking money from outside sources and that would clear most of this up, but they seem to fight it every step of the way.”
