Big Update For Lindsey Graham Hours Before South Carolina Primary

South Carolina Republicans head to the polls Tuesday in a closely watched U.S. Senate primary that has drawn national attention as the GOP works to protect its Senate majority ahead of the 2026 midterm elections.

Incumbent Sen. Lindsey Graham enters the final stretch with the endorsement of President Donald J. Trump and the backing of much of South Carolina’s Republican establishment.

His challenger, businessman Mark Lynch, is spending the closing days of the race responding to a growing series of controversies involving his finances, criminal history, campaign operations, and past public statements.

The latest issue stems from an exclusive report by the Washington Reporter, which alleged that Lynch’s most recent Senate financial disclosures show he has not yet paid between $50,000 and $100,000 in federal taxes for the 2025 tax year.

The report also alleged that Lynch failed to disclose bank accounts, investments, or other financial holdings that could explain approximately $5 million in personal contributions he has made to his Senate campaign.

According to the publication, an ethics complaint has been filed asking the Senate Ethics Committee to investigate Lynch’s financial disclosures and the source of his campaign funding.

Those financial questions add to an already difficult list of issues for Lynch.

Lynch has previously acknowledged a 1984 felony cocaine trafficking conviction, which he has described as part of a broader personal story involving addiction, rehabilitation, and redemption.

He has also claimed that he later received a presidential pardon.

However, recent reporting has raised questions about that claim. According to the Washington Reporter, searches of publicly available Justice Department pardon records have not uncovered documentation confirming that Lynch received a presidential pardon.

Reports have also indicated that Lynch recently acknowledged that neither he nor his attorney has been able to locate records supporting the pardon claim.

Additional scrutiny has focused on a 1985 South Carolina case involving allegations that Lynch left the scene of an accident involving injuries. Lynch has denied that the incident amounted to a hit-and-run.

According to State of the Day, court records show the original indictment was ultimately resolved after Lynch pleaded guilty to other charges.

Lynch has also faced criticism over past comments supporting the legalization of cocaine, remarks he later argued were taken out of context.

Questions have also been raised about campaign staffing decisions, with critics arguing that those choices reflected poor judgment in a race where Republicans cannot afford unnecessary distractions.

Graham and his allies have worked to make Lynch’s background a central issue, portraying the primary as a test of judgment, electability, and loyalty to President Trump’s broader Republican agenda.

The senator recently released an advertisement highlighting Lynch’s difficulty answering basic constitutional questions during a recorded interview.

President Trump has also weighed in forcefully.

The president endorsed Graham and sharply criticized Lynch, calling him a “LUNATIC” and warning that he would be a “DISASTER for the Republican Party.”

Over the weekend, however, Lynch received a high-profile endorsement from former Rep. Marjorie Taylor Greene.

“I am done watching Lindsey Graham sell out America,” Greene wrote on X.

Abby Zilch, a spokesperson for Graham’s campaign, framed the race as a choice between Republicans aligned with President Trump and factions she described as working against the president’s agenda.

“Senator Graham believes that South Carolina is Trump country, not MTG/Massie country,” Zilch said.

She added that Graham is proud to have the support of President Trump, Sen. Tim Scott, and what she described as legions of pro-Trump Republicans across South Carolina.

Polls indicate Graham maintains a sizable advantage heading into Election Day.

Still, South Carolina’s election rules require Graham to win more than 50 percent of the vote in order to avoid a runoff. That has added urgency to the closing days of the campaign, as the incumbent seeks to secure renomination outright and avoid an extended intraparty fight.

The race has increasingly centered on Lynch’s personal and financial controversies, giving Graham and his allies an opening to argue that South Carolina Republicans should not gamble with a Senate seat at a time when control of the chamber remains critical.

For conservatives, the stakes go beyond one primary. Senate Republicans are working to preserve their majority and support President Trump’s agenda on border security, immigration enforcement, taxes, judges, energy, and federal spending.

A prolonged runoff or a damaged nominee could create unnecessary complications in a cycle where Republicans want to stay focused on defeating Democrats, not cleaning up avoidable internal problems.

Lynch’s supporters argue that he represents frustration with the establishment and a demand for stronger conservative leadership. But his critics say the mounting questions surrounding his background make him a risky choice in a race with national consequences.

Whether the latest allegations change the outcome remains to be seen.

But as South Carolina Republicans prepare to vote, the choice has become increasingly clear: renominate a longtime senator backed by President Trump, or take a chance on a challenger now facing serious questions about his finances, past conduct, and readiness for federal office.
