WASHINGTON (AP) – Maine Sen. Susan Collins says she will vote to confirm Judge Ketanji Brown Jackson, giving Democrats at least one Republican vote and all but assuring that Jackson will become the first Black woman on the Supreme Court. Collins’ support Wednesday gives Democrats at least a one-vote cushion in the 50-50 Senate and likely saves them from having to use Vice President Kamala Harris’ tie-breaking vote to confirm President Joe Biden’s pick. It is expected that all 50 Democrats will support Jackson, though one notable moderate Democrat, Arizona Sen. Kyrsten Sinema, hasn’t yet said how she will vote.
