House Democrats have launched an investigation into a venture capital firm linked to Donald Trump Jr. following questions over its extraordinary growth and a series of government decisions that benefited companies in which it had invested.
Donald Trump Jr. became a partner at 1789 Capital just four days after his father won the 2024 presidential election.
At the time, the venture capital firm reportedly managed around $150 million. It now manages more than $3 billion, while its principal investment fund recorded a return of around 200% by the end of June 2026, according to House Judiciary Committee Democrats.
That rapid growth has attracted the attention of Jamie Raskin, the senior Democrat on the House Judiciary Committee, who has launched an investigation into whether the firm’s success has been helped by Donald Trump Jr.’s proximity to the White House.
Importantly, this is a congressional investigation into 1789 Capital and its dealings. Donald Trump Jr. has not been accused or charged with a criminal offence in connection with the inquiry.
Democrats demand records
Raskin has asked 1789 Capital to provide details of its portfolio companies, communications with federal officials, government actions affecting those investments and records surrounding Trump Jr.’s relationship with the firm.
He has also instructed the company to preserve communications with members of the Trump administration, including messages sent using encrypted applications.
Democrats argue that a pattern has emerged in which companies backed by 1789 Capital have subsequently received substantial government contracts, loans or regulatory decisions in their favour.
The firm and Trump Jr. deny that his political connections have provided 1789 Capital with an advantage.
The $620 million Vulcan Elements deal
Among the deals attracting particular attention is 1789 Capital’s investment in rare-earth magnet manufacturer Vulcan Elements.
The firm invested in Vulcan in 2025. Around three months later, the Pentagon announced plans for a $620 million loan to the company, alongside $50 million in incentives from the Commerce Department.
Vulcan’s estimated valuation subsequently increased from around $200 million to approximately $2 billion.
Reporting by ProPublica later found that the request for the Pentagon loan had originated with White House adviser Peter Navarro, a friend of Donald Trump Jr.
According to the investigation, Vulcan was the only one among dozens of companies being considered for funding whose deal had been initiated by a senior presidential aide.
Trump Jr.’s spokesperson said he had no involvement in the deal, did not discuss Vulcan with Navarro and had no knowledge of how the funding arrangement came together.
1789 Capital similarly said it played no role in securing the loan and did not know about it before it became public.
The Pentagon has said political affiliations and outside investors play no part in its funding decisions.
Juul and Polymarket also questioned
Raskin’s investigation also highlights investments involving e-cigarette company Juul and prediction market Polymarket.
1789 Capital acquired a stake in Juul before the US Food and Drug Administration authorised several of its products for sale.
The firm also invested in Polymarket, which subsequently benefited from the closure of a Justice Department investigation and regulatory decisions that allowed it to return to the US market.
Democrats say the timing warrants further examination. It does not, by itself, establish that Trump Jr. or 1789 Capital received advance information or influenced those decisions.
Billions in government awards under scrutiny
The investigation comes alongside a broader examination of companies associated with investment businesses linked to Donald Trump Jr. and his brother Eric Trump.
Earlier in August, Democratic lawmakers asked the Department of Defense’s inspector general to investigate reports that 15 companies associated with 1789 Capital and American Ventures had received around $3.2 billion in federal awards, with a further $3.1 billion available through potential future contract options.
The lawmakers said they wanted to establish whether political connections had played any role in the awarding of those contracts. The figures themselves do not establish wrongdoing, according to the House Oversight Committee Democrats.
Why November could change things
There is currently a significant limit on what Raskin and his Democratic colleagues can do.
Republicans control the House of Representatives, leaving Raskin as the ranking minority member of the Judiciary Committee rather than its chairman. Without support from the Republican majority, Democrats cannot simply use the committee’s subpoena powers to force 1789 Capital or Trump Jr. to hand over documents or appear for questioning.
For now, the investigation therefore depends heavily on voluntary cooperation.
That could look very different following November’s congressional elections.
Democrats are already preparing a much broader programme of investigations should they regain control of the House. A Democratic majority would control House committees from the beginning of the next Congress and could use subpoena powers to seek documents and testimony that minority members currently cannot compel.
If control of the Senate were also to change, Democratic-led Senate committees would have their own ability to launch investigations and call witnesses.
That does not mean the current allegations would automatically result in criminal proceedings. Congressional investigations are separate from investigations by law enforcement agencies.
But it would mean that questions which Democrats can currently ask could become questions that companies and witnesses may be legally compelled to answer.
1789 Capital rejects the allegations
1789 Capital has strongly rejected suggestions that its investments have benefited from improper access to the Trump administration.
A lawyer representing the company described Raskin’s allegations as unsubstantiated and characterised the investigation as politically motivated.
Trump Jr. has also maintained that he has no role in government policymaking and does not discuss the companies in which he invests with federal officials.
No evidence has yet established that Trump Jr. was given confidential government information or personally intervened to secure contracts or regulatory decisions for companies backed by 1789 Capital.
The investigation is now likely to focus on whether the documents requested by House Democrats reveal any connections between investment decisions at 1789 Capital and subsequent actions by the Trump administration.
For the moment, Democrats can request those answers.
After November, depending on who controls Congress, they may have considerably more power to demand them.
