RINGGOLD, Ga. (AP) — Republican Clay Fuller on Tuesday won Marjorie Taylor Greene’s former U.S. House seat in Georgia, turning back a Democratic challenge with the help of President Donald Trump’s endorsement.

Democrat Shawn Harris had led the first round of voting in March in a 17-candidate field, but couldn’t overcome the northwest Georgia district’s strongly Republican tilt.

Fuller’s arrival in the House bolsters a slim Republican majority. But he will have to run again later this year to secure a full two-year term.

Greene, once among Trump’s most ardent supporters, resigned in January after falling out with the president.

Trump’s endorsement boosted Fuller over Republican competitors but couldn’t win him a majority on March 10. However, the 12 total Republican candidates won nearly 60% of the vote. The 14th District is rated as the most Republican-leaning district in Georgia by the Cook Political Report.
