Zac Brown, the Grammy‑winning country singer, confirmed he will perform the National Anthem at UFC 250 on the White House South Lawn on May 26 , 2025. He remains the sole musical act after several performers exited over concerns about political overtones, and a lawsuit challenges the event’s legality.

May 26, 2025: UFC 250 to Take Place on White House South Lawn

According to the event’s organizers, the mixed‑martial‑arts showdown will be staged on the iconic South lawn, coinciding with Flag Day and former President Donald Trump’s 80th birthday. Around 8,000 active service members are expected to attend, and Brown will headline the fan fest before the fights.

Public Integrity Project Lawsuit Claims Federal Violations

The Public Integrity Project filed a complaint alleging the stage construction bypassed required congressional approval and failed to undergo an environmental review. As the report notes, the lawsuit argues the event may breach federal statutes governing the use of the White House grounds.

Artist Withdrawals Spark Political Debate

Several musicians pulled out of the lineup, citing perceived political bias and the proximity of the event to a presidential birthday celebration. Former President Trump publicly criticized the original roster, saying, "We don’t want singers with no talent… we’ve told them all to stay home," a comment that intensified the controversy.

Why Zac Brown Is Staying On

Brown, a self‑declared UFC fan , said he is "there for the troops, to honor America," emphasizing his patriotic motivation over any political affiliation. His decision makes him the only announced act, underscoring his willingness to face backlash for the cause he supports.

Unresolved Legal and Logistical Questions

Key uncertainties remain: Will a federal judge block the stage pending the lawsuit’s outcome? And how will security and environmental protocols be adjusted if the court finds procedural violations? The source does not provide details on any court rulings to date.
