President Donald Trump's pick for the Supreme Court was in the hot seat Tuesday as Connecticut's senior senator took his turn questioning her.

Senators have been grilling Amy Coney Barrett all day on everything from same-sex marriage rights, to gun laws, and even whether she would step aside if Trump disputes the election.

Barrett has not given many answers to any of those questions. Repeatedly she's said it would depend on the case before her, including whether to overturn Roe vs. Wade - which allows abortion.

Sen. Richard Blumenthal honed in on gun control, specifically, Connecticut's laws passed after the Sandy Hook shooting.

Those include a ban on AR-15 rifles and a limit on magazine rounds.

"Folks who live in Connecticut are terrified of that prospect, at least many of them who talk to me," said Blumenthal.

"Sandy Hook was a tragedy, so I express the deepest sympathy for those victims who've experienced that loss and elsewhere. But Kantor... I hope you take some comfort from Kantor being a much narrower decision that doesn't have any effect on those sorts of laws," said Barrett.

Barrett also said she can't commit to recusing herself if Trump disputes next month's election results.

"I certainly hope that all members of the committee have more confidence in my integrity than to think that I would allow myself to be used as a pawn to decide this election for the American people," she said.

Barrett is virtually guaranteed to be sworn in before the election.

On abortion rights, Barrett said Roe vs. Wade is not settled case law.
