Kamala Harris has just taken the oath of office.

She was sworn in by Supreme Court Justice Sonia Sotomayor.

This is the first time a woman, let alone a black and Asian American woman, has been inaugurated in one of the two highest positions in the US government.

She follows 48 men who have held the position of vice-president before her.

While I may be the first woman in this office, Harris vowed in her victory speech in November, I will not be the last, because every little girl watching tonight sees that this is a country of possibilities.
