The Supreme Court almost immediately granted Special Counsel Jack Smith’s Monday request for expedited consideration—a highly unusual rapid response that highlights the historic nature of the case.

Smith wants the court to weigh in on the question of whether former president Donald Trump has absolute presidential immunity for crimes he’s accused of carrying out while in the White House.

In its response, the high court ordered Trump’s attorneys to file a reply to Smith’s petition by next Wednesday, Dec. 20 at 4 p.m. ET.

The Supreme Court’s Monday decision does not mean it will take up the case—it simply means the nine-judge panel will make that decision on a much faster timeline than it normally would.
