Former Hunter Biden business partner Tony Bobulinski told lawmakers Wednesday that first brother James Biden “lied extensively” to congressional investigators last month about the degree of Joe Biden’s involvement in his overseas business dealings.

“Jim Biden … lied extensively throughout his transcribed interview on February 21, and perjured himself,” said Bobulinski, a former Navy officer who went in with James and first son Hunter Biden in a venture involving Chinese government-linked CEFC China Energy.
