Senate Majority Leader John Thune and Georgia Gov. Brian Kemp are increasing their backing for Republican Senate nominee Rep. Mike Collins as the party works to hold the chamber amid challenging political conditions.

Thune, R-S.D., and Kemp will headline a Sept. 24 fundraiser for Collins, the Republican nominee in Georgia's Senate race. The event underscores Republican efforts to maintain control of the Senate in the upcoming election cycle.

Collins, a member of the House from Georgia, faces a competitive contest. Republicans view the race as critical to their goal of retaining the majority. Party leaders have identified several battleground states where outcomes could determine Senate control.

Thune's involvement signals national Republican priorities. As majority leader, he plays a central role in coordinating support for key candidates. Kemp, a popular governor in Georgia, brings state-level influence to the effort.

The GOP faces headwinds in its bid to keep the Senate. Fundraising and candidate recruitment remain focal points in the final weeks before Election Day. Events like the upcoming fundraiser aim to bolster Collins's campaign resources.

Collins has positioned himself as a strong conservative voice in Congress. Supporters highlight his record on issues such as border security and economic policy. The race in Georgia is expected to draw significant attention from both parties.

Republican strategists continue to monitor polling and voter sentiment in the state. Additional high-profile appearances by party leaders are likely as the campaign progresses.
