President Donald Trump threw his weight behind Rep. Mike Collins (R-Ga.) in Georgia's Republican Senate runoff on Sunday, endorsing the congressman just two days before voters head to the polls in what has become a proxy battle between the president and Governor Brian Kemp.

Trump announced his support for Collins in an early-morning Truth Social post, praising the three-term congressman as someone who has "been with me from the beginning" and highlighting Collins' authorship of the Laken Riley Act—the landmark immigration enforcement bill that became one of the administration's first legislative victories.

A Trump-Kemp Rematch

The endorsement sets up a direct clash with Governor Kemp, who has backed Collins' opponent, former University of Tennessee football coach Derek Dooley. The Georgia governor and Trump have had a complicated relationship since 2020, when Kemp refused to overturn the state's presidential election results despite Trump's pressure campaign.

Collins, who represents Georgia's 10th Congressional District, has positioned himself as the MAGA champion in the race. His campaign has emphasized his close ties to Trump and his leadership on border security issues, particularly the Laken Riley Act, which requires federal detention of illegal immigrants accused of theft and violent crimes.

Dooley's Establishment Support

Dooley, who coached at Tennessee from 2010 to 2012, has garnered support from Georgia's Republican establishment, including Kemp and other state officials. The former coach has presented himself as a political outsider who can bring fresh perspectives to Washington, though critics note his lack of legislative experience.

The runoff became necessary after neither candidate secured a majority in the May 20 primary. Collins led the initial contest but fell short of the 50% threshold needed to avoid a second round of voting. The Tuesday runoff will determine who faces Democratic Senator Jon Ossoff in November's general election.

The Laken Riley Factor

Collins' signature legislative achievement has become central to his campaign identity. The Laken Riley Act, named after a University of Georgia nursing student allegedly killed by an illegal immigrant in February 2024, requires Immigration and Customs Enforcement to detain illegal immigrants accused of certain crimes.

The bill passed Congress with bipartisan support and was signed by Trump shortly after he took office in January 2025, marking one of the administration's earliest policy wins. Collins has repeatedly cited the legislation as evidence of his ability to deliver results on conservative priorities.

National Implications

The Georgia Senate race carries significant national implications as Republicans work to maintain their Senate majority. Ossoff, who won his seat in a January 2021 special election, has proven himself a formidable fundraiser and campaigner in the increasingly purple state.

Political analysts view Trump's late endorsement as a calculated move to maximize impact in the runoff's final hours while minimizing risk if Collins loses. An endorsement earlier in the race would have made a potential Collins defeat a more direct rebuke of Trump's political influence.

Early voting for the runoff has already concluded, meaning Trump's endorsement will primarily influence Election Day turnout. The president's team has indicated he may make additional statements supporting Collins before polls close on Tuesday.
