Exclusive: 'All talk and no action': Sicknick's mother and girlfriend say they were disappointed...

The mother of fallen US Capitol Police Officer Brian Sicknick says she was disappointed that Senate Republicans blocked a bill Friday to create a bipartisan commission to investigate the January 6 insurrection after what she described as "tense" meetings with many GOP senators on Thursday.

In an exclusive interview with CNN's Jake Tapper Friday, Gladys Sicknick and her son's girlfriend Sandra Garza said they were clinging to hope that they could change the minds of senators opposed to the independent commission, but were still not surprised at the ultimate outcome.

"They went through their motions, but you can tell that underneath they were being nice to us," Sicknick said of her meetings Thursday.

"I don't understand it. They are elected for us, the people, and they don't care about that," she added. "They care about money, I guess, their pocketbooks. So they'll be in front of the cameras when they feel like it. They just don't care, and it's not right."
