An attorney for President Donald Trump, his children and the Trump Organization told a Manhattan-based appeals court on Friday that two House committees had taken on an improper law-enforcement function in issuing subpoenas for Trump family financial records.

In oral arguments that stretched on for about 90 minutes, Patrick Strawbridge of Consovoy McCarthy said the subpoenas of records from Deutsche Bank and Capital One were the “broadest possible subpoenas ever served that target a sitting president” and lacked any legitimate legislative purpose.
