Companies backed by Donald Trump’s sons have won billions of dollars in Pentagon contracts since his election, ABC News reported.

The report says the Trump sons bet big on defence technology. Pentagon contracts then followed, raising questions about conflicts of interest.

The Washington Post reported that lawmakers have called for a Pentagon probe of Trump family-backed companies. They want to know if the deals were awarded fairly.

Yahoo reported on the scale of the defence tech investments. Critics say the pattern blurs the line between public office and private gain.

The White House has not detailed how the contracts were awarded. Ethics experts say the findings will fuel demands for tighter rules on presidential family business.

The Pentagon awards billions of dollars in contracts every year. Watchdogs say family ties to the White House demand extra scrutiny of such deals. Lawmakers want the probe to examine exactly how the contracts were won. Ethics lawyers say the findings could fuel new rules. The White House has dismissed the criticism as partisan.
