"We obtained that phone number and we've shared it with individuals and the Oversight Committee in Congress is going to subpoena those phone records. And what's important here is that's not a government phone, this is not Joe Biden's private phone that he's paying for himself. It's actually [Hunter] Biden's business that paid for it," Schweizer said during an interview with 77 WABC's Cats & Cosby, adding that it was discovered on Hunter's laptop that he was footing the bill for his father from 2009 to 2017, which is when Joe, 80, was Vice President.

"I think it's going to yield a lot of interesting information as to who Joe Biden was talking to on this phone that was being paid for by his son," he continued.

Schweizer also commented on the reported removal of the investigative team at the IRS looking into Hunter's alleged tax evasion. The reason for the removal came after a whistleblower contacted Congress about a possible cover-up going on at the IRS over the case.
