Sen. Lindsey Graham (R-SC) says he won’t endorse presumptive nominee Donald Trump because it won’t necessarily help the billionaire, but he was reportedly seen at a fundraiser urging people to unite behind Trump.

“Graham urged GOP donors at a private fundraiser Saturday in Florida to unite behind Trump’s campaign and stressed the importance of keeping likely Democratic nominee Hillary Clinton from the White House,” CNN reports. “The fundraiser was hosted by former U.S. Ambassador to Portugal Al Hoffman, a former Republican National Committee finance chairman who also co-chaired Sen. John McCain’s 2008 presidential bid.”

“He did say that we need to get behind him,” Teresa Dailey, who attended the private fundraiser, explained to CNN.

Kevin Bishop, Graham’s spokesperson, said Graham did attend the fundraiser, but didn’t confirm Graham’s statements on Trump.

“There hasn’t been any change in his position,” Bishop added. “He’s been pretty upfront and outspoken.”
