Republicans Seek FBI Files on Discredited Biden Informant
• Republicans demand FBI documents about informant Alexander Smirnov, who gave false testimony against Biden
• Smirnov claimed a Ukrainian company paid bribes to Hunter & Joe Biden, but was charged with lying
• His claims formed basis of Republican impeachment probe into Biden before Smirnov was exposed
• Republicans allege his arrest shows problems with FBI confidential informant program
• Comes after Republicans released Hunter Biden testimony defending his father; offered little new information
