Donald Trump Jr is helping his father pick the most controversial cabinet of modern times

Donald Trump Jr. influences cabinet picks, prioritizing loyalty and anti-establishment views, while advising his father in the White House.

Donald Trump Jr. has emerged as the most influential Trump family member in the transition as the president-elect builds the most controversial cabinet in modern U.S. history, according to a half dozen sources with knowledge of his role, elevating inexperienced loyalists over more qualified candidates for top positions in his administration.

Mr. Trump, who fiercely prizes loyalty, has long relied on family members for political advice, but which relative has his ear is known to vary.

This time, it is Don Jr., who has helped cabinet contenders sink or rise to the fore - from championing Senator J.D. Vance as Mr. Trump's running mate to blocking former Secretary of State Mike Pompeo from joining the cabinet, according to the sources, who include donors, personal friends and political allies.

Don Jr. is due to join conservative venture capital fund 1789 Capital, although one of the sources said he will continue to host his politics-focused podcast and support candidates that espouse Trump's brand of politics.

He will provide advice to his father in the White House, the source added, although they cautioned that Don Jr. was unlikely to be involved in day-to-day deliberations.

Don Jr. and the Trump-Vance transition team did not respond to a request for comment.

In addition to ensuring candidates are loyal to his father, Don Jr. typically seeks out contenders who embrace an anti-establishment worldview, including protectionist economic policies, and a reduction in military interventions and overseas aid, according to a handful of the sources and Don Jr.'s own comments on social media site X and in public.
