Lucy McBath is officially a Congressional representative.
The Democrat was sworn in to the 116th Congress, Jan. 3, joining one of the most diverse U.S. House cohorts in history.
McBath, along with her fellow freshman representatives participated in a ceremonial swearing in at the U.S. Capitol Thursday.
More than 100 women were sworn into the House of Representatives - a new record. But there are also other historic firsts - including for indigenous, Muslim and LGBTQ representatives.
McBath will represent Georgia's 6th District that covers north Atlanta, taking over from previous Republican representative Karen Handel.
The Democrat narrowly defeated Handle - who had just been elected to the post in a June 2017 special election to replace predecessor Tom Price - in the Nov. 6 election.

WHAT TO KNOW ABOUT LUCY MCBATH
McBath won a Democrat runoff against Kevin Abel in July, 2018. She is the mother of Jordan Davis, who was shot and killed in 2012 at a Jacksonville, Florida gas station by a man who objected to the loud music Jordan was playing in his car.
In a case that drew national attention, the gunman, Michael Dunn, used Florida's stand-your-ground law as his defense. He was not found guilty of murder in his first trial. In an October 2014 retrial, Dunn was convicted of first-degree murder and sentenced to life in prison.
After her son's death, McBath, who worked for Delta Airlines for 30 years, turned to politics. As national spokesperson for Everytown for Gun Safety, and Moms Demand Action for Gun Sense in America, she urged lawmakers to enact "common sense gun violence prevention laws."
