GOP's Comer faces backlash over Biden probe motives and FBI meeting request.

A White House memo obtained by NBC News accuses Republican Congressman James Comer of leading a politically motivated investigation into the finances of President Joe Biden's family. The memo argues that Comer's comments linking the investigation to Biden's poll numbers show that the probe is intended to damage the president politically. Comer is investigating foreign payments made to Biden's family members, but has yet to reveal any payments made to Biden directly. The memo draws a parallel between Comer's comments and Kevin McCarthy's linking of the Benghazi investigation to Hillary Clinton's poll numbers in 2013.
