Cheney slams GOP critics, calls Jan. 6 committee investigation 'deadly serious'

Ahead of Tuesday's House select committee hearing on the Jan. 6 Capitol assault, GOP Rep. Liz Cheney called the probe "deadly serious" on ABC's "Good Morning America,"

Hours before a House committee was set to open its investigation into the Jan. 6 Capitol assault, GOP Rep. Liz Cheney shot back at fellow Republicans criticizing her role in the probe, saying, "This is absolutely not a game. This is deadly serious." Appearing on ABC's "Good Morning America" Tuesday, Cheney lashed out at House GOP Leader Kevin McCarthy. ”There are some in my party, including Leader McCarthy, who continue to act as though this is about partisan politics, I think it's really sad. I think it's a disgrace,” she told ABC’s George Stephanopoulos. "The American people deserve to know what happened every minute of that day," Cheney said, accusing some Republicans of trying to "whitewash" the assault.
