Donald Trump Jr and Eric Trump, through the Trump Organization, made an investment in a construction company that is now positioned to profit from a rare earth minerals and tungsten deal in Kazakhstan backed by US government funding. The arrangement has drawn criticism over potential conflicts of interest given the sons' ties to their father, President Donald Trump, though a securities lawyer says there is little prospect of proving any wrongdoing.

Securities and investment fraud attorney Andrew Stoltmann said the deal "raises eyebrows" but that critics face a "proof problem" in establishing whether President Trump himself knew about or influenced the arrangement. The deal centres on a Kazakhstan-based tungsten and rare earth minerals project, with the Trump-linked construction firm set to benefit financially as the venture moves forward with US government funding support.
