Catherine Marie Cortez Masto (born March 29, 1964) is an American attorney and politician who is the junior United States Senator from Nevada. She is a member of the Democratic Party. She previously served as the 32nd Attorney General of Nevada from 2007 to 2015.
Catherine Marie Cortez Masto was Attorney General for less than 6 years.
It said she was Attorney general from 2007 to 2015 which is EIGHT years... so that she was it for less than 6 years is incorrect.
