WASHINGTON >> When President Donald Trump directed his attorney general last month to investigate online fundraising, he cited concerns that foreigners and fraudsters were using elaborate “schemes” and “dummy accounts” to funnel illegal contributions to politicians and causes.

Instead of calling for an expansive probe, however, the president identified just one potential target: ActBlue, the Democrats’ online fundraising juggernaut, which has acknowledged receiving over 200 potentially illicit contributions last year from foreign internet addresses.

Trump’s announcement contained a glaring omission — his political committees also received scores of potentially problematic contributions.

An Associated Press review of donations to Trump over the past five years found 1,600 contributions from donors who live abroad, have close ties to foreign interests or failed to disclose basic information, often making it difficult, if not impossible, to identify them and verify the legality of their donations Among those was $5,000 linked to a derelict building, and $5,000 from a Chinese businessman who listed a La Quinta Inn as his address. Another sizable donation — $1 million — was made by the wife of an African oil and mining magnate.

It’s against the law for U.S. candidates and political committees to accept contributions from foreign nationals. Laws also place strict limits on donation amounts and prohibit the laundering of contributions to get around legal caps. For the most part, such donations have been policed by campaigns and the Federal Election Commission, with only the most egregious examples being targeted by federal law enforcement.

But after reclaiming the White House, Trump embarked on a campaign of retribution against his perceived enemies, launching broadsides against universities, law firms and his own former officials. If the Justice Department were to investigate ActBlue, it could imperil a key fundraising tool for Trump’s political rivals before the 2026 midterm elections, when Republicans’ threadbare House majority — and the president’s ability to pass an agenda through Congress — will be on the line.

“This is him taking direct aim at the center of Democratic and progressive fundraising to hamstring his political opponents,” said Ezra Reese, an attorney who leads the political law division at the Elias Law Group, a leading Democratic firm that does not represent ActBlue. “I don’t think there’s any question that they picked their target first. He’s not even pretending.”

The White House did not respond to questions about Trump’s fundraising, including what sort of fraud prevention measures his committees have in place. Instead, a senior administration official pointed to the findings of a recent House Republican investigation of ActBlue that the White House alleges “uncovered specific evidence of potentially unlawful conduct.”

“The memorandum directs the attorney general to investigate this matter broadly, and she will follow the evidence and take appropriate action as warranted,” said the official, who insisted on anonymity to discuss the matter.

Neither the Justice Department nor Trump’s 2024 campaign co-manager Chris LaCivita responded to requests for comment.

U.S. citizens living abroad are free to donate to politicians back home. But it can be difficult even for campaigns to discern who is allowed to give and whether a person may be serving as a “straw” donor for someone else seeking to influence U.S. elections.

The AP identified only two Trump donors out of more than 200 living abroad whose U.S. citizenship was listed as “verified” in the president’s campaign finance reports. He received over 1,000 contributions from 150 donors who omitted key identifying details such as their city, state, address or country. Trump also received at least 90 contributions from people who did not give a full name, are listed as “anonymous” or whose donations include the notation “name not provided.”

Many of these Trump donors contributed through WinRed, the Republicans’ online fundraising platform that is the GOP’s answer to ActBlue. Only about three dozen of these contributions were rejected, most of which came from an unknown source and were paid in cryptocurrency, campaign finance disclosures show.

WinRed officials did not respond to a request for comment.

“Foreign money in our elections is a legitimate concern,” said Dan Weiner, a former Federal Election Commission attorney who is now director of the Brennan Center’s elections and government program. “What’s not legitimate is to single out one political opponent and pretend the problem is limited to them.”

Jiajun “Jack” Zhang, for example, is a jet-setting Chinese businessman whose Qingdao Scaffolding Co. boasts of being one of the “biggest manufacturers and suppliers in China” of scaffolding. In October, he used WinRed to donate $5,000 to Trump, campaign finance disclosures show.

Zhang lives in China’s Shandong province, according to his LinkedIn account, and is described in French business filings as a Chinese national. But his contribution to Trump lists a La Quinta Inn in Hawaiian Gardens as his address, records show. The donation was made around the time that Zhang posted a photo on social media of his family visiting Disneyland, which is near the hotel.

Zhang did not respond to an email seeking comment.

Other potentially troublesome donations include four from unnamed donors listing an address of “999 Anonymous Dr.”

There is also a series of contributions made through WinRed that listed the donor’s address as a vacant building in Washington that was formerly a funeral home. The donor, identified only as “Alex, A” on Trump’s campaign finance report, gave nearly $5,000, spread across more than 40 separate transactions last year. Those types of donations tend to draw scrutiny from campaigns and regulators.

Regulators and watchdogs have also long been concerned about donations from individuals with ties to foreign interests. Trump has received many such contributions, including one in December from Nnenna Peters, the wife of Benedict Peters, a Nigerian billionaire who is the founder and CEO of oil and mining businesses.
