Fox News reports that John Robinson Walker has been asked to appear before the House Oversight Committee in order to provide testimony on the matter. 

Walker is the man whom the House Oversight Committee recently discovered sent Chinese-based cash to multiple members of the Biden family. There will be more on this in a minute.

But, U.S. Rep. James Comer (R-KY), the chairman of the House Oversight Committee, has now asked Walker to testify before the committee.

Comer has described Walker as a "critical witness."

The backstory

Recently, Comer and Republicans on the House Oversight Committee released a memo detailing "New Evidence Resulting from the Oversight Committee’s Investigation into the Biden Family’s Influence Peddling and Business Schemes.”

It turns out that the committee subpoenaed Walker's bank records, and it is there that the committee found that Walker had previously sent Chinese-based money to members of the Biden family.

According to Comer, the bank records show that, “over the course of several years, members of the Biden family and their companies received over $1.3 million in payments from accounts related to their associate, Rob Walker.”

Those Biden family members include Hunter Biden, James Biden, Hallie Biden, and a yet-unidentified Biden.

Comer went on to say that "most of this money came as a result of a wire from a Chinese energy company." But, Comer said that he doesn't know why the money was sent to the Bidens.

A "critical witness"

It is in conjunction with this discovery that the House Oversight Committee wants Walker to provide testimony.

"Rob Walker is a key witness in our investigation of President Biden’s involvement in his family’s business schemes, Comer said on Friday.

This quote comes from the letter that Comer sent to Walker asking him to testify. Comer additionally writes:

When speaking about dealings with the Biden family, Rob Walker once said that exposing him would "bury all of us, man." Why? The Oversight Committee has many questions for Rob Walker and we look forward to getting answers for the American people.

Comer, in the letter, asks Walker to get in touch with committee staff by March 24 in order to set up the interview, which would be a transcribed interview before the committee. It remains to be seen whether or not Walker will provide the testimony.

In the meantime, President Joe Biden has denied the accusations brought by the House Oversight Committee. Additionally, a White House spokesperson called some of the allegations - particularly the one involving Hallie Biden - as "disgusting."
