US Senator Lindsey Graham, the chairman of the Senate Judiciary Committee, said Supreme Court nominee Judge Amy Coney Barrett is in a "category of excellence" during his opening statements of her confirmation hearing this morning, CNN reports.

"In my view, the person appearing before this committee is in a category of excellence, something the country should be proud of, and she will have a chance to make her case to be a worthy successor and to become the ninth member of the Supreme Court of the United States," Graham said.

He also praised the late Justice Ruth Bader Ginsburg, saying that during her confirmation hearing almost every Republican senator voted for her based on her qualifications.

"I just want to remind everybody, there was a time in this country where someone like Ruth Bader Ginsburg was seen by almost everybody as qualified for the position of being on the Supreme Court, understanding that she would have a different philosophy than many of the Republicans who voted for her," Graham said, drawing parallels to Barrett.

As Republicans are expected to push the hearing forward with speed and Democrats look for ways to draw out the process for the lifetime appointment, Graham called for senators to use the hearing as an opportunity to learn more about Barrett.

"The hearing is a chance for Democrats to dig deep into her philosophy, appropriately ask her about the law, how she would be different, what's on her mind. It gives Republicans a chance to do the same thing," he said about Barrett.

Senator Lindsey Graham, says the US should be proud of Judge Amy Coney Barrett.
