Attorneys For Hunter Biden and James Biden Refusing to Cooperate with Senate Committees Posted on Senators Chuck Grassley (R-IA) and Ron Johnson (R-WI) on Saturday said attorneys for Hunter Biden and James Biden are refusing to cooperate with senate committees. “After issuing our report on September 23 on the conflicts of interest and foreign financial entanglements of the Biden family, Senator Grassley and I have continued to seek information and testimony from the individuals involved,” Johnson said referring to the bombshell senate report on Burisma corruption. "Attorneys for Hunter and James Biden have refused to cooperate with the committees. It should be noted that, collectively, President Trump’s family and associates produced documents and agreed to appear at interviews with a number of congressional committees,” the GOP senators said in a statement.
