The Supreme Court on Tuesday issued a brief rejection of Republicans' attempt to overturn President-elect Joe Biden's victory in Pennsylvania.

Why it matters: The GOP request denied on Tuesday was the first petition to delay or overturn election results on behalf of the Trump campaign to reach the high court.

• President Trump's ongoing legal fight to overturn the race results has not gone far, as federal judges in states including Georgia and Michigan have rejected the campaign's unfounded claims of mass voter fraud.
• Biden's win in Pennsylvania helped to cement the final outcome of the 2020 election as a key battleground state.
