Jackson faced down a barrage of Republican questioning Wednesday about her sentencing of criminal defendants  as her history-making bid to join the Supreme Court veered from lofty constitutional questions to attacks on her motivations on the bench.

In her final day of Senate questioning, she declared she would rule “without any agendas” as the high court’s first Black female justice and rejected Republican efforts to paint her as soft on crime in her decade on the federal bench.

The GOP criticism at her confirmation hearing was punctuated with effusive praise from Democrats, and by reflections on the historic nature of her nomination — none more riveting in the room than from New Jersey Sen. Cory Booker, who used his time not to ask questions but to tearfully speak and draw tears from Jackson as well.

Booker, who is Black, said that he sees "my ancestors and yours"  when he looks at her. “I know what it’s taken for you to sit here in this seat,” he said. “You have earned this spot.”

Jackson was silent as Booker talked, but tears rolled down her face, her family sitting behind her.

Jackson was in tears a second time after similar praise from Sen. Alex Padilla, and responded to the California Democrat that she hopes to be an inspiration because “I love this country, because I love the law.”

Though her approval seems all but sure — Democrats are aiming for a vote before Easter — Republicans kept trying to chip away at her record.
