Handel succeeded Tom Price, who resigned from the seat following his confirmation as United States Secretary of Health and Human Services in the Trump administration.

Following Price's resignation, Governor Nathan Deal called for the special election to be held on April 18,[1] with a filing window for prospective candidates from February 13 to 15, 2017.

A total of $50 million was spent as of the close of early-voting period on June 17, making it the most expensive House election in history.

[56][57] Because no candidate secured an absolute majority, the top two-vote-getters, Ossoff and Handel, competed in a runoff election on June 20, 2017.

[61] Ossoff's opponent, Karen Handel, and national Republican groups attacked Ossoff for raising significant small-dollar contributions from outside of Georgia, although Handel's campaign received the bulk of its support from super PACs and other outside groups, including those funded anonymously by so-called "dark money".

[62][63] Combined spending by the campaigns and outside groups on their behalf added up to over $55 million, which was the most expensive House Congressional election in U.S.
