The sons of President Donald Trump are set to profit from a massive mineral deal in Asia, prompting outrage that the First Children are intertwined with the administration's efforts to secure rare earth materials.

The President and Commerce Secretary Howard Lutnick helped close a mining deal in Kazakhstan last year after Trump made the final pitch on a call with the Asian country's president.

Kaz Resources, an American company, has preliminary approval to mine one of the largest tungsten deposits globally using up to $1.6 billion in federal funding, and it has ties to Don Jr and Eric Trump.

Dominari Securities - a financial firm partly owned by the Trump brothers that is located in Trump Tower - took a 20 percent stake in a company related to the project, according to the New York Times. 

Kaz Resources expects that the total resources at the site could be worth up to $80 billion, according to the firm. 

'Neither Don nor Eric has any involvement in this transaction,' a spokesperson told the Daily Mail. 'They are, and have always been, passive investors with absolutely no management role in this vehicle.' 

Brandon and Kyle Lutnick, the sons of the commerce secretary, through their company Cantor Fitzgerald, helped raise $210 million for an investor working with Dominari on the deal. 

The investor, ASP Isotopes, then independently got involved in the Kaz Resources deal. A Cantor Fitzgerald spokesperson told the Daily Mail that the firm was not directly involved in the mining agreement. 

'Cantor's involvement is limited to supporting capital raises in the public markets and does not include participation in negotiations with the current or any prior administration,' the spokesperson said in a statement. 

The billion-dollar deal has prompted outrage among the administration's critics who are concerned that the Trump and Lutnick families are enriching themselves during the President's second term.

'Right in front of our faces. Zero attempt to hide or conceal it. Absolute, total self-enrichment at a magnitude we have never really seen,' journalist Isaac Saul reacted to the deal. 'And every week brings a new story just like it. They're getting richer at every opportunity.' 

California Democratic Congressman Mike Levin wrote on social media: 'The fathers set the policy. The sons cashed in ... Either we will end the corruption, or the corruption will be the end of us.' 

Trump skeptics have also voiced concern over the President's family profiting from crypto as the Republican has sought to loosen regulations on the sector. 

The Trump family has earned at least $1.2 billion in cash through its crypto company, World Liberty Financial, the Wall Street Journal reported in February. 

The family of Steve Witkoff, the President's special envoy currently handling US-Iran peace talks, reportedly made $200 million from the crypto venture, which they have invested in.
