President Donald Trump accused two of the nation’s largest banks of rejecting his business, as his administration was preparing an executive order threatening financial institutions who refused to work with certain customers on ideological grounds.

The Trump administration is expected to take additional efforts to crack down on perceived bias against conservatives in the financial system.

Shares of JPMorgan Chase & Co. (NYSE: JPM) and Bank of America Inc. (NYSE: BAC) are trading lower Tuesday after President Donald Trump claimed the two banks discriminated against him by refusing to accept large deposits.
