Among the conflicts are Lutnick's involvement in the crypto industry and federal and state cases against Cantor Fitzgerald.
In addition to running the Wall Street firm, Lutnick is a banker for the "stablecoin" company Tether; purchasers receive a Tether token for $1, with the proceeds invested in reserves and Treasury bonds managed by Lutnick's Cantor Fitzgerald.
As Public Citizen noted, New York Attorney General Letitia James found in 2021 that Tether and another crypto firm "recklessly and unlawfully covered up massive financial losses to keep their scheme going and protect their bottom lines."
The company is also reportedly under federal investigation over alleged criminal violations of anti-money laundering rules and sanctions.
Public Citizen also said that while co-chairing Trump's transition team, Lutnick "may also have helped arrange a meeting between Trump and Coinbase chief Brian Armstrong," who "helped steer a record amount of political spending from the crypto industry into the 2024 election."
Crypto firms poured over $119 million into directly influencing the 2024 federal elections, Public Citizen found in August, making the industry's spending second only to that of fossil fuel companies.
As Politico reported in October, even other members of Trump's inner circle have accused Lutnick of using his transition team co-chair position to take meetings on Capitol Hill and "talk about matters impacting his investment firm, Cantor Fitzgerald—including high-stakes regulatory matters involving its cryptocurrency business."
Lutnick's nomination, said former Labor Secretary Robert Reich, serves as a reminder that "Trump serves the oligarchy, not the people."
"Debris from crypto's political spending tsunami will jam up more halls in Washington than ever before if Lutnick is confirmed as secretary of commerce," said Bartlett Naylor, a financial policy advocate for Public Citizen. "The president-elect, who once correctly called bitcoin a scam, now surrounds himself with even more crypto enablers. Cryptocurrency won't return good jobs to the heartland or reduce food prices; it will only thin the wallets of those vulnerable to a now government-legitimized con."
Government watchdog Accountable.US pointed to more than $19 million in political donations Lutnick has made since 2009, nearly all of which went to GOP candidates and political action committees. He contributed $6 million to Trump's super PAC, Make America Great Again, Inc., in 2024 alone.
"Howard Lutnick's questionable qualifications to lead the Department of Commerce begin and end with his loyalty to the president-elect," said Accountable.US executive director Tony Carrk.
Tether isn't the only Lutnick-linked company that's been investigated for wrongdoing. The Securities and Exchange Commission fined Cantor Fitzgerald $1.4 million in 2023, saying the company repeatedly failed "to identify and report customers who qualified as large traders." The company also agreed to pay $16 million in fines to the SEC and the Commodity Futures Trading Commission in 2022 for using unauthorized communication channels.
Should Lutnick be confirmed as commerce secretary, Accountable.US said a "major regulatory conflict" could arise due to a dispute between the BGC Group, a spin-off brokerage of Cantor Fitzegerald, and futures and commodities exchange CME Group, over a competing trading platform BGC Group is launching.
"Lutnick's company's violations resulting in financial regulator fines and millions in right-wing political donations shows that political devotion takes precedence over actual experience to do the job in Trump's Cabinet," said Carrk.
Trump campaigned as a champion of working people as he railed against high grocery prices. As The New Republicreported on Tuesday, Lutnick has showered Trump's plan for across-the-board tariffs with effusive praise—even as leading economists warn the plan to impose tariffs on foreign imports will pass higher costs onto consumers, not foreign countries.
"In September, Lutnick told CNBC that 'tariffs are an amazing tool for the president to use—we need to protect the American worker,'" wrote Edith Olmsted. "Lutnick also gushed about tariffs at Trump's fascistic rally in Madison Square Garden last month, claiming that America was better off 100 years ago, when it had 'no income tax and all we had was tariffs.' His high praise for tariffs came even as he admitted Americans would face higher prices as a direct result."
Lutnick's nomination, said Sen. Elizabeth Warren (D-Mass.), "is a win for the billionaire class at the expense of working people."
"The across-the-board tariff plan," she said, "is a distraction from the MAGA scam to extend tax giveaways for giant corporations and billionaires like Howard Lutnick."
