Clay Fuller, President Donald Trump's pick to replace former GOP Rep. Marjorie Taylor Greene, won a special election in Georgia Tuesday night, according to the Associated Press.

Fuller won with 54% of the vote compared to Democrat Shawn Harris, who secured 46% at time of publishing, with 45% of the vote counted. 

Fuller and Harris placed in the top two positions in a March special election, leading to Tuesday's runoff. The district is heavily Republican and Fuller was the solid favorite to win the seat.

Fuller's arrival in Congress is expected to prove a boost to House Speaker Mike Johnson, who has struggled to maintain unity within the narrow Republican majority.
