Republican presidential nominee Donald Trump seized on reports Monday that a longtime ally of Hillary Clinton arranged for more than $500,000 in campaign contributions to the wife of an FBI official involved in the probe of her secret email server.

The Wall Street Journal reported that Virginia Gov. Terry McAuliffe’s PAC in 2015 donated nearly $500,000 to state Senate candidate Jill McCabe, whose husband now is deputy director of the FBI. In addition to the $467,500 in campaign cash, the Virginia Democratic Party paid for mailers on her behalf, worth another $207,788.

“So the man who was investigating her from the FBI, his wife runs for office, and they give her more than $670,000 to run. And it just came out. They just figured it out.”

At a rally in St. Augustine, Florida, on Monday, Trump repeated the news and then dramatically walked away from the podium as the crowd booed lustily. When he returned to the microphone, he characterized the affair as another piece of evidence of a corrupt political system.

“So the man who was investigating her from the FBI, his wife runs for office, and they give her more than $670,000 to run,” he said. “And it just came out. They just figured it out.”

Trump tied the campaign payments to Clinton, who has been close to McAuliffe since he served as chief fundraiser for her husband’s first presidential campaign in 1992. Trump said the donations to Jill McCabe indicate why FBI Director James Comey decided not to recommend criminal charges against Clinton in connection with her handling of classified information on the private server she had installed in the basement of her suburban New York home as secretary of state.

“This represented a large portion of the money the FBI official’s spouse had for the entire campaign — a big, big percentage. It’s absolutely disgraceful. It’s absolutely terrible,” he said. “And it’s unbelievable how Hillary Clinton got away with the email lie, the email scam, the email corruption. But now at least, we have a pretty good idea.”

For Trump, the revelation is a gift to a campaign that has been trying to make an issue of fraud and favoritism in the political system.

“Our system is rigged,” he said. “She never had a chance to be convicted. Hillary knew this money was being paid, and she has to be held accountable for this — yet another crime, one of so many.”

A spokesman for McAuliffe downplayed the significance of the contributions, arguing that they were an attempt to win control of the state Senate for the Democrats and not an effort to influence the Clinton investigation. In addition, FBI officials determined that the involvement of the candidate’s husband, Andrew McCabe, was not an ethics issue because his wife’s campaign was over by then.

The Washington Examiner reported that Jill McCabe’s opponent, current state Sen. Dick Black, called for Andrew McCabe to resign.

“I call on Andrew McCabe to step down from the FBI for the good of all the agents who do their work in ethical and honest fashion,” he told the Examiner. “What he has done has hurt the FBI.”

Black told the Examiner that the donations made the McCabe family “indebted” to McAuliffe.

Indebtedness to McAuliffe could have been a benefit not only to Clinton but the governor himself.

CNN reported in May that the FBI was investigating whether McAuliffe improperly accepted $120,000 in campaign contributions from a Chinese businessman. Foreign nationals are not permitted to donate to U.S. election campaigns.
