Devon Archer, Hunter Biden's former business partner, testifies before House Oversight Committee

Devon Archer, a former business associate of Hunter Biden, met with lawmakers behind closed doors on Monday to testify about the younger Biden's business dealings and what, if any, involvement his father, President Joe Biden, had with them.

Archer and his attorney Matthew Schwartz were on Capitol Hill for several hours for an interview with the Republican-led House Oversight Committee.

Archer was expected to provide details related to Hunter Biden's business dealings in Ukraine, ABC News previously reported.

Archer subsequently told lawmakers on Monday that Hunter Biden would frequently take his father's phone calls in the company of business associates and put him on speakerphone, according to lawmakers and sources familiar with the testimony -- a development that sparked partisan jockeying over its significance.

James Comer, the Republican chairman of the Oversight Committee, called it evidence that "Joe Biden lied to the American people when he said he had no knowledge about his son's business dealings and was not involved."

Democrats framed those interactions as benign pleasantries: "Not a shred of evidence of a single conflict of interest of President Biden ever doing anything in connection or in relation to Hunter Biden's business ventures," said Rep. Dan Goldman of New York.
