Sen. Tom Cotton (R-AR) suggested President Joe Biden could come to regret the recent pardon he granted on Sunday, arguing the president’s son could be required to provide testimony in Congress.

The president’s pardon was granted to his son, Hunter Biden, regarding all “offenses against the United States which he has committed or may have committed or taken part in” over an 11-year period, marking a reversal from how he said he would not issue such a pardon. When asked what this pardon would mean for any future investigations by the Senate or the incoming Trump administration into the Biden family, Cotton contended people need to “wait and see” who else the president could pardon, be it other family members of Hunter Biden’s “corrupt businessmen.”
