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.

Big banks said they agree with President Donald Trump that financial regulations need an overhaul, even as their stock prices dropped Tuesday after the president confirmed plans to issue an executive order to punish those that he said discriminate against conservatives.
