Factual error in your video. The VA legislature did not vote for secession, a special convention called into being by the legislature did so.

On November 15, 1860 Virginia Governor John Letcher called for a special session of the Virginia General Assembly to consider, among other issues, the creation of a secession convention. The legislature convened on January 7 and approved the convention on January 14. On January 19 the General Assembly called for a national Peace Conference, led by Virginia’s former President of the United States, John Tyler, to be held in Washington on February 4, the same date that elections were scheduled for delegates to the secession convention.[5]
