President-elect Donald Trump is asking the Supreme Court to delay his planned sentencing Friday in his criminal hush money case, setting up a potential test of the high court's ruling to extend broad immunity from prosecution to former presidents.

Trump's lawyers argued that the justices should step in and pause his sentencing "to prevent grave injustice and harm to the institution of the presidency."

Supreme Court Justice Samuel Alito spoke with President-elect Donald Trump about a former law clerk the day before Trump went to the high court in a push to delay the sentencing in his New York hush-money case.
