WASHINGTON (AP) — Hundreds of demonstrators are gathering outside the Supreme Court to protest Donald Trump's election.

They are mostly young people who appear to have walked out of school to protest.

They are carrying signs that read "Black Lives Matter" and "Not My President." Another signs says "DCPS Walkout Help Stop Trump." DCPS stands for District of Columbia public schools.

The protesters walked from Trump's newly opened hotel at the Old Post Office Building on Pennsylvania Avenue and past the Capitol.

The Supreme Court is across the street from the Capitol. The streets in between are blocked by protesters and police.
