Former President Donald Trump on Saturday detoured from his tour of battleground states on the last weekend before election day to Virginia, where he urged the state’s attorney general to open an investigation into Rep. Nancy Pelosi’s stock trading. 

During a rally in Salem, Virginia, Mr. Trump was in the midst of his usual stump speech where he decried Ms. Pelosi, California Democrat, for working behind the scenes to get President Biden off the ticket in favor of Vice President Kamala Harris when he pushed Republican Virginia Attorney General Jason Miyares to “look at” her stock trading habits.

Ms. Pelsoi doesn’t trade stocks but does show massive gains in her financial disclosures. She and her husband Paul Pelosi, who owns San Francisco-based investment and consulting firm Financial Leasing Services, Inc., have been hit with criticism for playing the market and for the enormous wealth she has accumulated since taking office in 1987. 

According to Quiver Quantitative, a data firm that tracks lawmakers’ portfolios, Ms. Pelosi has a trade volume of roughly $137 million. 

Mr. Trump, who has long traded barbs with the former Speaker of the House, implied that Mr. Pelosi, working off information from Ms. Pelosi, sold 2,000 shares of Visa stock worth around $500,000 roughly two months before the Justice Department filed a lawsuit against the company.  

“Mister Attorney General, I think this is most important for you,” Mr. Trump said. “I don’t know, maybe you can, maybe you could look at it. You know, you touch that little Washington area a little bit, so maybe you can look at it.”

“Because you know what, she’s a crook, and she’s been doing that for years,” he continued. “She’s been doing that crap for years. You ought to look at her.”

He also congratulated Mr. Miyares for his win earlier this week when the Supreme Court allowed Virginia to move forward with its removal of roughly 1,600 alleged noncitizens from its voter rolls just days before the election. 

Earlier, Mr. Trump was in battleground North Carolina, where he will return Saturday night for a rally, and will hit Pennsylvania, Georgia and North Carolina again on Sunday. 

But he diverted from his tour of swing states to visit Virginia, a state Republicans haven’t won since former President George W. Bush in 2004. President Biden blew out Mr. Trump there by 10 points four years ago. 

Ms. Harris may not win Virginia and its 12 electoral votes by the same margin, but she is ahead of Mr. Trump by an average of 5.8 points, according to polling aggregate Real Clear Polling. 

But Mr. Trump and Republicans believe the blue stronghold is in play this cycle. 

“Now it’s very possible that without winning Virginia, we’re going to win the whole thing too, but it’d be — wouldn’t it be cool? Wouldn’t it be nice? We got to do it,” Mr. Trump said. “We’re going to win, Virginia, I really believe it, we felt it, your governor [Glenn Youngkin] felt it. I felt it for a long time.”
