Partner of fallen Capitol officer Brian Sicknick "disgusted" by senators who stopped January 6 commission

Gladys Sicknick, the mother of Brian Sicknick — the U.S. Capitol Police officer who died after supporters of former President Trump stormed the building on January 6 — said her final interaction with her son was brief. 

"He texted me, he says, 'I'm busy right now, I can't talk,'" she told CBS News' Nikole Killion. "And that was the last I heard from him."

Sicknick and her son's longtime partner Sandra Garza were on Capitol Hill last week to lobby lawmakers to vote for an independent commission to investigate what happened on January 6. 

Senate Republicans blocked the effort on Friday.
