Trump made 175 financial transactions in March, mostly bonds issued by states, counties, school districts, and public agencies.

His portfolio has around $337 million in bond purchases, many of which are in areas that could benefit from his policy initiatives

Trump bought Intel bonds after ordering the government to buy a 10% share in the chipmaker. Netflix and Warner Bros. cost him up to $2 million. Discovery bonds shortly after a $72 billion merger.

Although legal, these purchases have sparked worries about potential conflicts of interest, The White House says these investments are managed by independent third-party financial organizations.

Financier Kevin Warsh, Trump’s Federal Reserve chair nominee, is set to succeed Jerome Powell, who leaves office on May 15. Warsch said he didn’t pledge to receive the job despite Trump’s selection.

Trump has chastised Powell for not reducing interest rates faster since his second tenure. Doing so may stimulate economic activity but also inflation.
