RICHMOND, Va. (AP)- Virginia Attorney General Mark Herring is making his re-election bid official.

Herring announced in a public letter and video released early Wednesday morning that he would seek a third term. The Associated Press has previously reported that Herring told several elected officials of his plans in September.

Herring is a former state senator who became attorney general in 2014. He easily won re-election in 2017 as the growth in northern Virginia continues to drive the Commonwealth solidly blue.

Herring has been a frequent critic of the president and a vocal supporter of same-sex marriage, immigrant-friendly policies and stricter gun control.
