That was on Republican congress on one of those picks. They denied Obama a pick that should have been his, because it came at the last of his term.(1 year before it ended which wasn't the last of his term
) Three or four months is the last of your term.
It should be a 5-4 majority not a 6-3 majority for Republicans. That would have changed the abortion vote and likely others too. Abortion was 5-4 to overturn. Would have been 5-4 to not overturn if Obama's pick was in, instead of Trump's first pick. A Republican congress obstinately stole that pick for Trump. He didn't do anything for that 'gift'.
